MCQ

$\text{IUPAC}$ name of the compound $\mathrm{CH}_3-\mathrm{CH}\left(\mathrm{CH}_2 \mathrm{CH}_3\right)-\mathrm{CH}_2-\mathrm{CH}(\mathrm{OH})-\mathrm{CH}_3$ is:

A
$4-$Ethyl$-2-$pentanol
✓
$4-$Methyl$-2-$hexanol
C
$2-$Ethyl$-2-$pentanol
D
$3-$Ethyl$-2-$hexanol

✓

Answer

Correct option: B.

$4-$Methyl$-2-$hexanol

Longest carbon chain has $6$ atoms. We number from right hand side as alcohol group at $C-2$ gets least number in this case and suffix used for alcohol is $''-ol\ ''.$ Methyl group is present at $C-4$ position.
Thus$, \text{IUPAC}$ name is $4-$Methyl$-2-$hexanol.
