Question

The calcium salts of carboxylic acids on dry distillation gives:

• A. alcohols
• B. aldehydes
• C. ketones
• D. either aldehydes or ketones

Answer 1

The correct option is D either aldehydes or ketones

Dry distillation of calcium salts of carboxylic acids gives either aldehydes or ketones.
For example, when calcium acetate $\left(\right(C{H}_{3}COO{)}_{2}Ca)$ is heated, acetone $(C{H}_3-CO-C{H}_3)$ and calcium carbonate $\left(CaC{O}_3\right)$ are obtained.
Also, when calcium formate $\left(\right(HCOO{)}_{2}Ca)$ is heated, formaldehyde $\left(HCHO\right)$ and calcium carbonate $\left(CaC{O}_3\right)$ are obtained.
