MCQ

Ethyl alcohol exhibits acidic character on reacting with:

A
Acetic acid
✓
Sodium metal
C
Hydrogen iodide
D
Acidic potassium dichromate.

✓

Answer

Correct option: B.

Sodium metal

$\mathrm{CH}_3 \mathrm{CH}_2-\mathrm{OH}+\mathrm{Na} \rightarrow \mathrm{CH}_3-\mathrm{CH}_2-\mathrm{O}^{-} \mathrm{Na}^{+}+ \frac {1}{2}\mathrm{\sim H}_2$
Acid reacts with metal to give hydrogen gas.
Hence, in above reaction $\mathrm{CH}_3 \mathrm{CH}_2 \mathrm{OH}$ behaves as an acid.
