Text Solution

Verified by Experts

The correct Answer is:
C

Given compound
`CH_(3)CH=CHCH_(2)CHBrCH_(3)`
may also be written as follows :

Both geometrical isomerism (cis-trans form) and optical isomerism is possible in this compound.
Number of optical isomer `= 2_(n) = 2^(1) = 2`
(Here n = number of asymmetric carbon)
Therefore, total number of stereoisomers
`=2+2=4`
