1. Pure HCI is gas.2. Pure benzoic acid is solid.
3. All carboxylic acids (no of carbons larger than 8) and aromatic acids are white solid.
OR the carboxylic acids with more than 2 –COOH.
(Because more inter-H bonds.)

At 20 °C and 1 atm, linear carboxylic acids are liquids up to nonanoic acid (nine carbon atoms) and solids beginning from decanoic acid (ten carbon atoms). Aromatic carboxylic acids, the simplest being benzoic acid, are solids.
