An organic compound A reacts with PCl(5)...

An organic compound A reacts with `PCl_(5)` to give compound B. Compound B reacts with Na/ether to give n-butane. What are compounds A and B ?

A

`C_2H_5OH and C_2H_5Cl `

B

`C_2H_5Cl and C_2H_5ONa`

C

`C_3H_7OH and CH_3CH_2CH_2OCl`

D

`C_4H_9OH and C_4H_9OCl`

Text Solution

Verified by Experts

The correct Answer is:
A
(a) Since B undergos Wurtz reaction to give n-butane , B is ethyl chloride.
(b) `C_2H_5OH + PCl_5 overset(Delta)to C_2H_5-Cl + POCl_3+HCl`
Therefore A is ethanol.
