Total number of stereoisomers of the given compound is:
Options:
Answer:
B
Solution:
Ans. (B) 4.
Sol. The molecule, (CH3CHCl)2C=C(Br)CH3, has two stereocentres. They are constitutionally equivalent, but the (R,S) form is not meso: the plane that would exchange the two halves would also have to swap Br and CH3 on the alkene carbon, so no internal compensation exists. Hence all 22 = 4 forms, (R,R), (S,S), (R,S) and (S,R), are distinct.
