i. sodium
ii. potassium permanganate solution.

ii. potassium permanganate solution.
✓
Answer
i. With sodium metal, sodium ethoxide is formed.
$2 CH _3 CH _2 OH +2 Na \longrightarrow 2 CH _3 CH _2 ONa + H _2$
ii. With alkaline potassium permanganate, ethanol is oxidised to ethanoic acid.
$CH _3 CH _2 OH +2[ O ] \xrightarrow{\frac{K M n O_4}{d i . H_2 SO _4}} CH _3 COOH + H _2 O$
$2 CH _3 CH _2 OH +2 Na \longrightarrow 2 CH _3 CH _2 ONa + H _2$
ii. With alkaline potassium permanganate, ethanol is oxidised to ethanoic acid.
$CH _3 CH _2 OH +2[ O ] \xrightarrow{\frac{K M n O_4}{d i . H_2 SO _4}} CH _3 COOH + H _2 O$
