Question

Identify the main functional derivative of carboxylic acid.

• A. Ester
• B. Alkane
• C. Alcohol
• D. None of these

Answer 1

The correct option is A Ester

Ester is the main functional derivative of carboxylic acid. Ester has general formula $R-\underset{\underset{O}{||}}{C}-O{R}^{\prime }$. Carboxylic acid has general formula $R-\underset{\underset{O}{||}}{C}-OH$. An example of ester is ethyl acetate $C{H}_3-\underset{\underset{O}{||}}{C}-O-C{H}_2-C{H}_3$. An example of carboxylic acid is acetic acid $C{H}_3-\underset{\underset{O}{||}}{C}-OH$
