Which of the following products is obtained in Highest yield when 2-bromopentane is treated with `CH_(3)CH_(2)O- Na^(+)` ?

A

trans-`CH_3CH = CHCH_2CH_3`

B

cis- `CH_3CH = CHCH_2CH_3`

C

`H_2C = CHCH_2CH_2CH_3`

D

2-pentanol

Text Solution

Verified by Experts

The correct Answer is:
A
There are three possible products. These are cis- `CH_3CH = CHCH_2CH_3`, trans- `CH_3CH = CHCH_2CH_3 and H_2C=CHCH,CH_2CH_3`
The-most substituted alkene is produced with the highest yield as predicted by the Saytzeff.s rule, with trails dominating over cis.
