Show Answer

Answer:

Correct Answer: 37. (2)

Solution:

  1. (7) As given in the question 3 stereocentres are visible, i.e.

Hence, the total number of stereoisomers $=2^{3}=8$

But out of these the following one is optically inactive due to symmetry

Hence, total number of optically active stereoisomers $=7$
