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_(3)CH=CHCH_(2)CH_(3)`

B

cis- `CH_(3)CH =CHCH_(2)CH_(3)`

C

`H_(2)C = CHCH_(2)CH_(2)CH_(3)`

D

2-pentanol

Text Solution

Verified by Experts

The correct Answer is:
A
There are three possible-products, These are cis-`CH_(3)CH=CHCH_(2)CH_(3)` trans- `CH_(3)CH=CHCH_(2)CH_(3)` and `H_(3)C =CHCH_(2)CH_(2)CH_(3)`.
The most substituted alkeneis produced with the highest yield as predicted by the SaytzefFs rule, with trans.dominating over cis.
