Question

Molecules exists as a pair of enantiomers is:

• A. $2$-cyclohexen-$1$-ol
• B. $2$-chloropropane
• C. $1$-chloro-$3$-methylbutane
• D. none of these

Answer 1

The correct option is A $2$-cyclohexen-$1$-ol

Enantiomers are chiral molecules that are mirror images of one another. Furthermore, the molecules are non-superimposable on one another. This means that the molecules cannot be placed on top of one another and give the same molecule. Hence 2-cyclohexene-1-ol exist in a pair of enantiomers.
