The molecule has 4 stereoisomers.
This can be obtained only if you first draw an open structure of the compound then from there you go as follows;
CH3CH=CHCH2C*BrCH3
So then in the first instance we can say that between the carbon atoms having the double bond, we have a geometric isomer.
The carbon which have (*) has optical isomer.
Thus in the above formula, we have only one chiral carbon. So there are 2 stereogenic center.
Then to find the number stereoisomers use the formula 2^n; 2^2 = 4 stereoisomers.
