Q.77) How many products (including stereoisomers) are expected from monochlorination of the following compound?
A) 6
B) 2
C) 3
D) 5
Q.77) Product I and III have one chiral centre, hence they give $\left(2^n=2^1=2\right)$ two optical isomers as products.
Total products $=2+1+2+1=6$
Hence, the correct answer is option (1).
