Question

Toppr Admin · Accepted Answer

With an increase in the molecular weight, the boiling point increases. With an increase in $O H$ groups, the extent of hydrogen bonding increases, and boiling point increases.

Due to above two reasons, (IV) Hydroxybenzene has a lowest boiling point.

(I) 1,2-Dihydroxybenzene (II) 1,3-Dihydroxybenzene (III) 1,4-Dihydroxybenzene (IV) HydroxybenzeneThe increasing order of boiling points of above-mentioned alcohols is:I<II<III<IVI<II<IV<IIIIV<I<II<IIIIV<II<I<III

With an increase in the molecular weight, the boiling point increases. With an increase in OH groups, the extent of hydrogen bonding increases, and boiling point increases.Due to above two reasons, (IV) Hydroxybenzene has a lowest boiling point.

(I) $1, 2$ -Dihydroxybenzene (II) $1, 3$ -Dihydroxybenzene (III) $1, 4$ -Dihydroxybenzene (IV) Hydroxybenzene
The increasing order of boiling points of above-mentioned alcohols is:
$I < I I < I I I < I V$
$I < I I < I V < I I I$
$I V < I < I I < I I I$
$I V < I I < I < I I I$

With an increase in the molecular weight, the boiling point increases. With an increase in $O H$ groups, the extent of hydrogen bonding increases, and boiling point increases.

Due to above two reasons, (IV) Hydroxybenzene has a lowest boiling point.
