The increasing order of the boiling points for the following compounds is:

$(I)$ $C_{2} H_{5} OH$ $(II)$ $C_{2} H_{5} Cl$ $(III)$ $C_{2} H_{5} {CH}_{3}$ $(IV)$ $C_{2} H_{5} {OCH}_{3}$

Question

The increasing order of the boiling points for the following compounds is: I C 2 H 5 OH II C 2 H 5 Cl III C 2 H 5 CH 3 IV C 2 H 5 OCH 3

TestHub · Accepted Answer

Boiling Point ∝ Dipole moment ∝ H - bonding in the molecules C 2 H 5 CH 3 < C 2 H 5 OCH 3 < C 2 H 5 Cl < C 2 H 5 OH , C 2 H 5 OH - O - H bond present . Boiling point also increases with the increasing molecular mass.
