Which of the following orders is true regarding the boiling point of organic substances?

A

`CH_(3)COCl gt CH_(3)COOH gt (CH_(3)CO)_(2)O`

B

`CH_(3)COCl lt CH_(3)COOH lt (CH_(3)CO)_(2)O`

C

`CH_(3)COCl gt CH_(3)COOH lt (CH_(3)CO)_(2)O`

D

`CH_(3)COCl lt CH_(3)COOH gt (CH_(3)CO)_(2)O`

Text Solution

Verified by Experts

The correct Answer is:
B
`CH_(3)COCl` does not involve hydrogen bonding. Its boiling point is lesser than `CH_(3)COOH.` The boiling point of the latter is lesser than that of `(CH_(3)CO)_(2)O` due to large molar mass of `(CH_(3)CO)_(2)O`.
