Question

Which gas will release when phenol react with sodium metal ?

• A. Hydrogen
• B. Oxygen
• C. Carbon dioxide
• D. Reaction does not take place

Answer 1

The correct option is A Hydrogen

Phenol reacts with sodium to form sodium phenoxide and hydrogen gas. The hydrogen atom in the $-OH$ bond is replaced by a sodium atom. Hydrogen in $-OH$ bond is reduced to hydrogen gas while sodium is oxdised to $N{a}^{+}$ ion. This is an acid-metal reaction.
