Select all correct statements about the compound shown.

AThe anion has three topologically different kinds of ring hydrogen
BOn acidification of its aqueous solution benzoic acid separates
CIts aqueous solution is acidic
DHeating it with soda lime gives benzene

Answer: A, B, D

The compound shown is sodium benzoate. Acidification protonates the anion to give the sparingly soluble benzoic acid. It is the salt of a weak acid and strong base so its solution is basic, not acidic. The ring has ortho, meta and para H (3 environments, checked by RDKit). Decarboxylation with soda lime gives benzene.
