Write the reaction equations: СН4 – С2Н2 – СН3СОН –СН3СООН – (CH3COO) 2Mg.

1) 2CH4 = C2H2 + 3H2 (when heated, methane decomposes into acetylene and hydrogen, decomposition reaction);

2) C2H2 + H2O = CH3COH (when acetylene interacts with water, acetaldehyde is formed, Kucherov’s reaction);

3) CH3COH + Ag2O = CH3COOH + 2Ag (when acetaldehyde interacts with silver oxide, acetic acid is formed, the “silver mirror” reaction);

4) CH3COOH + Mg (OH) 2 = (CH3COO) 2Mg + H2O (when acetic acid reacts with magnesium hydroxide, magnesium acetate and water are formed, hydrolysis of esters).



One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
