The IUPAC name for -

\[ \text{CH}_3\underset{\substack{\textstyle | \\[-0.2ex] \textstyle \text{O}\rlap{\text{H}}}}{\text{C}}\text{HCH}_2\overset{\substack{\textstyle \text{C}\rlap{\text{H}_3} \\[-0.2ex] \textstyle |}}{\underset{\substack{\textstyle | \\[-0.2ex] \textstyle \text{O}\rlap{\text{H}}}}{\text{C}}}\text{CH}_3 \] is:

पर्याय

• 1, 1-Dimethylbutane-1,3-diol

• 4-Methylpentane-2, 4-diol

• 2-Methylpentane-2, 4-diol

• 1, 3, 3-Trimethylpropane-1, 3-diol

Answer 1

2-Methylpentane-2, 4-diol

Explanation:

The longest continuous carbon chain has 5 carbons (pentane). Numbering from right to left gives the lowest positions to the groups: a methyl group and an \(-\text{OH}\) group at carbon-2, and another \(-\text{OH}\) group at carbon-4.
