Question

Indicate the stereo centres in the following molecule and total number of stereoisomers in the following molecule.

Answer 1

Chiral centers are centers which has four assymetric carbons attached to it as shown in the figure.

Here four configurations are possible as these two chiral centers are different.

$⟹\begin{array}{cc}R& R\\ R& S\\ S& R\\ S& S\end{array}⟹$4 stereoisomers
