$I$. $2 CH_3 Br \xrightarrow[\text{dry ether}]{Na}$
$II$. $CH_3 COOH \xrightarrow[CaO, \Delta]{NaOH}$
$III$. $CH_3 CH=CH_2 \xrightarrow{H_2 / Pt}$
$IV$. $CH_3 CH_2 Br \xrightarrow[H^{+}]{Zn}$
Correct answer is

The correct order of boiling points of the following molecules is:
$(i)$ $n$-Hexane
$(ii)$ $2$-methylpentane
$(iii)$ $2,3$-dimethylbutane

$1,3-$Dibromopropane is heated with zinc dust in ether. The product formed is
