Solution

(a)Sodium reacting with ethyl alcohol:

$2 C_{2} H_{5} O H + 2 N a ⟶ 2 C_{2} H_{5} O N a + H_{2}$

When sodium reacts with ethyl alcohol hydrogen is evolved with the formation of sodium ethoxide.

(b) Ethanol oxidized by $K_{2} C r_{2} O_{7}$ :

$C_{2} H_{5} O H [O] - ---- \to K_{2} C r_{2} O_{7} C H_{3} C H O + H_{2} O [O] - ---- \to K_{2} C r_{2} O_{7} C H_{3} C O O H$

Alcohols get oxidized and get converted into ethanal and then into acetic acid.
