There were many metal-related substances that could react with alkyne. The following were common situations: 1. Alkali metal: For example, metal Na or Li can reduce alkyne in liquid nitrogen, but liquid nitrogen solution of Na cannot be used to reduce terminal alkyne. 2. ** Metal-organic reagent related metal **: When the organic lithium reagent acts with HMP A, lithium is involved. When the organic lithium compound reacted with HMPA, its molecular structure was easily deagglomerated, which accelerated the reaction. This process was related to metallic lithium. 3. ** Metal with a catalyst **: For example, in the synthesis of alkynes, the Lindlar catalyst is usually used. It is made by attaching palladium-based catalyst (Palladium-based catalyst) to a small amount of lead dioxide. This catalyst can reduce alkynes to alkynes, and the resulting alkynes have a uniform configuration, which is the cis-configuration. 4. Metal in specific reactions: For example, in China's original carbon dragon chemistry research results, there was the reaction of ossium (Os-carbyne) with alkyne in the carbon dragon complex ring. This reaction revealed a new reaction mode between the carbon-carbon triple bond and the carbon-metal triple bond. In addition, in some reactions, when metal ions were involved in the reaction, Hexamethylphosphorous acid (HMPA) could be used as a co-catalyst to improve the reaction conditions, which also implied that a variety of metal ions (specific metal ions were not specified, but metal ions were involved in the reaction) could be associated with alkyne-related reactions under suitable conditions.

Why can two substances react?

The fundamental reason for the reaction of matter was the movement of matter and the changes in the surrounding environment, including physical and chemical changes. From a chemical point of view, one situation was that a substance would become an ion. The ion would collide in a solution, and the collision with a certain amount of energy would form a combination (effective collision). The S and P orbitals of the outer electrons would form a bond with the S orbitals of other substances, and a chemical change would occur. For example, in some solution reactions, the effective collision of ions would promote the reaction. There were also some cases where the interaction between the metal ions (such as Mn, Mn, etc.) and the metal ions (Mn, Mn, etc.) would result in the formation of a deposit of the metal ions. This was also a manifestation of the reaction. In addition, when there were too many Cl-ions and too many NH3 molecules, it would cause silver ions, copper ions, etc. to form a complex with Cl-ions and NH3 molecules. This was also a reaction. The chemical reactions between substances had mutual transformation and opposition relations. For example, there was a mutual transformation relationship between metals, metal powders, alkali-based and salt-based, non-metals, non-metal powders, acid and salt based on elements, while there was a reaction relationship between metals and non-metals, basic powders and acidic powders, alkali-based and acid, salt-based and salt based on opposites. From a physical point of view, if it snowed in winter, it was the water vapor in the air that cooled down and solidified due to the rotation of the earth. When the temperature rose, the snow melted. This was a change in the state of matter caused by the change in the physical environment. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Why do substances react faster in solution?

From a microscopic point of view, when a solute was dissolved, the molecules or ions of the solute would spread into the water and be evenly dispersed among the water molecules. This allowed the molecules of the two substances to come into contact with each other more fully during the chemical reaction, so the reaction was faster. From the perspective of contact area, the solution was a uniform and stable mixture. In the solution, the contact area of the two substances was large, and the chemical reaction rate was fast. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

A class of substances that can react with acid to produce gas

There were several types of substances that could react with acid to produce gas: 1. Metal activity ranked before H. This type of metal would undergo a displacement reaction with acid to release gases, such as Na, MG, AI, and Fe. 2. For example, CaCOcan react with acid to form CO2, and NaHCOcan also react with acid to form carbon dioxide. 3. Sulfites and bithites react with strong acid to form sulfur dioxide gas. For example, when BaSO2 react with acid, it will form SO2. 4. Metal Sulfides and Sulfur Hydrides react with strong acid to form hydrogen Sulfates, such as Sulfur Sulfides, which react with acid to form H ^S (generally believed to require concentrated sulfuric acid). 5. The corresponding salt of a weak acid would react with a strong acid to form an acidic gas, and react with a strong base to form an aromatic gas. For example, the reaction of an aromatic acid with an acid would form carbon dioxide, and the reaction of an aromatic acid with a base would form aromatic gas. 6. Special substances such as Mn <2>, which can produce Cl2 by oxidisation of HQ (requires concentrated HQ); F <2> can also produce Cl2 by oxidisation of HQ. 7. When a bleacher is mixed with an acid (such as vinegar), it will produce Cl2. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

How to determine whether two substances can react

To determine whether two substances could react, the following factors needed to be considered: 1. Distinguish between chemical changes and physical changes: chemical changes often produce light, heat, color changes, gas production, and other phenomena. The essence is the formation of new substances (from a macro perspective) or new molecules (from a micro perspective). Physical changes are the opposite, such as glass shattering, material melting, vaporizing, etc. 2. ** Considering material properties **: - ** Reactant Nature **: The closer the nature of the reagent, the higher the possibility of the reaction. - ** Oxidability and Reductibility **: If it is an oxido-reduction reaction, a reaction may occur when one substance has a strong oxidisation and the other has a strong reduction. 3. ** Pay attention to reaction conditions **: - ** Temperatures **: Generally, raising the temperature can increase the kinetic energy of the reagent particles, increasing the probability of collision and thus promoting the reaction. - ** Concentration **: The higher the concentration of the reagent, the higher the probability of collision and the easier the reaction to occur. - ** catalyst **: Although the catalyst does not participate in the reaction, it can reduce the activation energy of the reaction and accelerate the reaction. 4. ** Judgment of reaction type **: - ** Metathesis reaction **: See if there are any hard-to-dissolve substances, hard-to-ionise substances, and volatile substances. - ** Other reactions **: You can determine whether a reaction has occurred by detecting the changes in temperature, color, gas volume, and other physical and chemical properties before and after the reaction. At the same time, for the ion reaction, if it was an oxido-reduction reaction, it could be judged according to the periodic table of the elements. The reduction of the elements in the same period from left to right was from strong to weak, and the oxidization from weak to strong. It could also be judged according to the reaction conditions. Different oxidisers (or reducing agents) reacted with the same reducing agent (or oxidiser). The easier the reaction was, the stronger the oxidiser (or reducing agent) of the corresponding oxidiser (or reducing agent). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Why is helium not easy to react with other substances to release heat?

Helium was an inactive element with a stable atomic structure. Under normal circumstances, it could not react with other elements. This was because the outermost layer of the helium atom was full of electrons, so it was difficult to gain and lose electrons. Therefore, it was difficult to have a chemical reaction with other substances, and it was also difficult to react with other substances to release heat. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
