Dehydration of which one of the following alcohols produces an alkene exhibiting cis-trans isomerism ?

A

Isopropyl alcohol

B

Tertiary butyl alcohol

C

Secondary butyl alcohol

D

3-Pentanol

Text Solution

Verified by Experts

The correct Answer is:
C
Both `2^@` butyl alcohol and 3-pentanol on dehydration give alkenes which show cis-trans isomerism.
