Question

Arrange the following in increasing/decreasing order of boiling point :
CH3CH2CH2CH2CH3I, (CH3)2CHCH2CH3II, (CH3)4CIII
  1. I > II > III
  2. II > I > III
  3. III > I > II
  4. III < II < I

A
II > I > III
B
III < II < I
C
III > I > II
D
I > II > III
Solution
Verified by Toppr

The decrease order of the boiling point is CH3CH2CH2CH2CH3I>(CH3)2CHCH2CH3II>(CH3)4CIII.
As the extent of branching increases, the boiling point decreases.
