Question

For a given alkyl group the boiling point of alkyl halides follow the order, *

a) R – I > R – Cl > R – Br

b) R – Cl > R – Br > R – I

c) R – I > R – Br > R – Cl

d) R – Br > R – I > R – Cl​

Answer 1

Explanation:

b) R - Cl > R - Br > R - I

it is due to decrease in strength of R-X bond with the increase in size
