An alkyl bromide (X) reacts with sodium in ether to form 4,5-diethyloctane. The compound 'X' is

A

`CH_3(CH_2)_3 Br`

B

`CH_3(CH_2)Br`

C

`CH_3(CH_2)_3CH(Br)CH_3`

D

`CH_3-(CH_2)_2-CH(Br)-CH_2CH_3`

Text Solution

Verified by Experts

The correct Answer is:
D
`2CH_3-(CH_2)_2-oversetoverset(" "CH_2CH_3)|CH-Br+2Na underset"(Wurtz reaction)"overset"Dry ether"to underset"4,5-Diethyloctane"(overset1CH_3-overset"2-3"((CH_2))_2-oversetoverset(" " CH_3CH_2)|underset4" CH"-oversetoverset(" " CH_2CH_3)|underset5" CH"-overset"6-7"((" " CH_2)_2)-overset8CH_3-2NaBr)`
Thus , option (d) is correct.
