Question

Consider the following molecule


The number of stereogenic centres and stereoisomers respectively of the above molecule are:

• A. $8,2^9$
• B. $9,2^9$
• C. $10,2^{10}$
• D. $10,2^9$

Answer 1

The correct option is A $8,2^9$


Where (*) represents a stereogenic centre.
Out of the two double bonds one double bond can show geometrical isomerism while other one doesn't show due to restricted structure.
Double bond is not considered as stereogenic centres.
So, total number of stereogenic centers $=8$
Total number of stereoisomers $=2^9$
