Question

The correct order of increasing boiling point of the following compound is:
$\begin{array}{cccc}C{H}_{3}CON{H}_2& C{H}_{3}COCl& C{H}_{3}COOC{H}_3& C{H}_3-\stackrel{\stackrel{O}{||}}{C}-O-\stackrel{\stackrel{O}{||}}{C}-C{H}_3\\ \left(I\right)& \left(II\right)& \left(III\right)& \left(IV\right)\end{array}$

• A. I < II < III < IV
• B. II < III < IV < I
• C. II < IV < III < I
• D. II < III < I < IV

Answer 1

The correct option is B II < III < IV < I

II < III < IV due to the compound's higher molecular weight and (I) has got the highest boiling point because of the presence of $H$ bonding.
