Rank the following substances in order of increasing boiling point (Lowest

\to

Highest).

\begin{array}{cccccccccccccccccccc} {{\text{a}}{\text{.}}\,\,\,C{H_3}C{H_2}C{H_2}C{H_2}OH}&{{\text{b}}{\text{.}}\,\,\,{{\left( {C{H_3}} \right)}_2}CHOC{H_3}}&{{\text{c}}{\text{.}}\,\,\,{{\left( {C{H_3}} \right)}_3}COH}&{{\text{d}}{\text{.}}\,\,\,{{\left( {C{H_3}} \right)}_4}C} \end{array}

View answer and explanation

Correct option: C

d < b < c < a

Option C (d < b < c < a) is correct because boiling point increases with increasing molecular weight and hydrogen bonding, and decreases with branching.
