Question

$C_5{H}_{12}O$ is a monohydric alcohol. How many isomers of this alcohol are possible? How many of these contain chiral centers as well as can exhibit enantiomerism?

• A. 8 and 3
• B. 6 and 2
• C. 4 and 2
• D. 12 and 4

Answer 1

The correct option is A 8 and 3

There are total 8 isomers possible with molecular formula $C_5{H}_{12}O$ which are monohydric alcohols i.e with one $OH$ group. Among 8 isomers, there are three isomers (highlighted) that contain chiral carbon/ center i.e. carbon with all four different groups attached. These are optically active centers and exhibit enantiomerism.
