59 gram of an amide obtained from a carboxylic acid (RCOOH) upon heating with alkali liberated 17g of `NH_(3)` The acid is :

A

Formic acid

B

Acetic acid

C

Propionic acid

D

Benzoic acid

Text Solution

Verified by Experts

The correct Answer is:
B
(b) `underset(59g("1 mole"))underset()(RCONH_(2))+NaOHrarrRCOOH+underset(17g)underset()NH_(3)`
Molar mass of `RCONH_(2)`
`R+12+16+14+2=59`
`R=59-44=15=CH_(3)`
`therefore` Acid is `CH_(3)COOH`.
