Question

(1) Arrange the following Alkyl halides in increasing order of their
Boiling point.
(CH3)3C-CI,CH3-CH2-CH2-CH2-CI,(CH3)2 CH-CH2-CI
1+1=2
​

Answer 1

Answer:

Increasing order of boiling point :

${\sf{\red{CH_3CH_2CH_2CH_2Cl}}}$ < ${\sf{\red{(CH_3)_2CHCH_2Cl}}}$ < ${\sf{\red{(CH_3)_3CCl}}}$

Explanation:

This is due to the fact that when there is a branching in the chain, then the surface area of the compound decreases and it looks like a Sphere and hence, the boiling point also decreases.

Therefore, straight chain compounds have the highest boiling point.

And increase in branching results decrease in boiling point.
