Question

Interference C2 h5 CL, C2 h5 BR and C2 h5 I in increasing order of their boiling point

Answer 1

Interference C2 h5 CL, C2 h5 BR and C2 h5 I in increasing order of their boiling point

Hey mate here is your answer.

The Br and iodine has lower molecular weight as compared to Cl so as having   higher  the molecular weight so higher is the boiling point.... Hence, ethyl chloride has higher boiling point

hope this answer will help you.
