JEE Main 2017 — Chemical Bonding and Molecular Structure Question with Solution

JEE Main 2017 (09 Apr Online)

Question

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

IC2H5OH      IIC2H5Cl    IIIC2H5CH3   IV C2H5OCH3

Choose an option

Show full solutionCorrect option: C
Correct answer
CIII<IV<II<I

Step-by-step explanation

Boiling Point∝ Dipole moment∝H-bonding in the molecules

C2H5CH3<C2H5OCH3<C2H5Cl<C2H5OH,

C2H5OH-O-H bond present.

Boiling point also increases with the increasing molecular mass.
