The total number of cyclic structure as well as stereoisomers possible for a compound with the molecular formula `C_(5)H_(10)` is:

Options

A. (a) 7
B. (b) 9
C. (c) 12
D. (d) 13

Answer

A

Explanation

`C_(5)H_(10)=IDU`. It can be cyclic and cab be alkene.
Therefore, total cyclic and stereoisomers = 7
If it is alkane: Me

Other alkene structure:

Total number of cyclic, acyclic, and stereoisomers is 13. However, in the problem only cyclic structural and steroisomers have been asked. So the total number of isomers would be seven.
