Question
How many stereoisomers does this molecule have

$CH_3CH=CHCH_2CH(Br)CH_3$

✓

Answer

c
The number of stereogenic centres which comprises of optically active carbon and the carbon showing geometrical isomerism. In the above picture, there is only one geometric isomer and chiral carbon. So, there is $2$ stereogenic centre.

stereoisomers $=2^{ n }=2^2=4$
