Question

Name the following compounds according to IUPAC system

${CH}_3-\underset{\stackrel{|}{{CH}_3}}{CH}-{CH}_2-\underset{\underset{OH}{|}}{CH}-\stackrel{\stackrel{{CH}_{2}OH}{|}}{C}H-{CH}_3$

Answer 1

The IUPAC name for the given compound is $2,5$-dimethylhexan-$1,3$-diol.

$2,5$-dimethyl is for the methyl group $(-C{H}_3)$ attached at $C-2$ and $C-5$ each, and hexan-$1,3$-di-ol is for the long chain of $6$ carbon atoms with alcohol group $(-OH)$ at $C-1$ and $C-3$ each.

Hence the IUPAC name for the given compound is $2,5$-dimethylhexan-$1,3$-diol.
