Vedclass · Answer

(A) The given compound is $1,3,5$-trimethylcyclohexane. It has three chiral centers at positions $1, 3,$ and $5$. Due to the symmetry of the molecule,we can have different stereoisomers: $1$. All-cis isomer (all three methyl groups on the same side): This molecule has a plane of symmetry and is achiral (meso). $2$. Trans-cis isomer (two methyl groups on one side,one on the opposite side): This molecule also has a plane of symmetry and is achiral (meso). Thus,there are only $2$ stereoisomers,both of which are optically inactive. Therefore,the correct option is $A$.

The total number of stereoisomers formed by the given compound is:
