Question

How many chiral centers and stereoisomers are present in the given compound?

• A. $3,18$
• B. $2,8$
• C. $4,16$
• D. $3,6$

Answer 1

The correct option is B $2,8$

It has two chiral centres and it can be divided into two equal halves.
Hence total number of enantiomers $2^n=2^2=4$

Since the compound contains a double bond and exhibits geometrical isomerism, it will have total of eight stereoisomers four from each of cis and trans isomers.
