Fill in the blanks and rewrite the balanced equation. C 6 H 5 - COOH + _____ → ∆ _____ + phosphorous oxychloride + HCl

When benzoic acid is treated with PCl 5 , benzoyl chloride is obtained, including POCl 3 and HCl as a side product. Phosphorus V chloride is a solid which reacts with carboxylic acids in the cold to give steamy acidic fumes of hydrogen chloride. It leaves a liquid mixture of acyl chloride and a phosphorus compound, phosphorus trichloride oxide (phosphorus oxychloride). The acyl chloride can be separated by fractional distillation. The complete and balanced chemical reaction is as follows: C 6 H 5 - COOH + PCl 5 → ∆ + C 6 H 5 - COCl + POCl 3 + HCl .

Fill in the blanks and rewrite the balanced equation. _____ NH 3 _____ → ∆ C 6 H 5 - CONH 2

Carboxylic acids react with ammonia to form ammonium carboxylate salt which on further strong heating at high temperature decomposes to give an acid amide. The balanced chemical reaction is as follows: C 6 H 5 - COOH ⇌ NH 3 C 6 H 5 COONH 4 → ∆ C 6 H 5 - CONH 2 + H 2 O .
