Let’s write down the reaction equations:
H3C – CH3 + Cl2 = H3C – CH2 – Cl + HCl – substitution reaction;
H3C – CH2 – Cl + KOH = H3 – CH2 – OH + KCl – exchange reaction;
H3C – CH2 – OH + CuO = H3C – CH2O + CU + H2O – alcohol oxidation reaction, acetaldehyde is formed;
alcohol oxidation reaction, acetaldehyde is formed;
H3C – CH2O + Ag2O = H3C – COOH + 2Ag – silver mirror reaction, aldehyde is oxidized to acetic acid.
The solution shows the genetic relationship of organic substances: alkanes, alcohols, aldehydes and carboxylic acids.
