Question

Choose the correct option.

Which of the following represents the increasing order of boiling points of (1), (2), and (3)?

(1) \[\ce{CH3 - CH2 - CH2 - CH2 - OH}\]

(2) (CH₃)₂CHOCH₃

(3) (CH₃)₃COH

Options

• (1) < (2) < (3)

• (2) < (1) < (3)

• (3) < (2) < (1)

• (2) < (3) < (1)

Answer 1

The boiling point of alcohol in the increasing order is (1)<(2)< (3)

Explanation 

• primary alcohol has a higher boiling point as compared to secondary boiling point. This is due to the property of the formation of the hydrogen bond. For the conversion of the liquid state to the gaseous state, there should be much more separation between the compounds

• as a result of these two separate the two molecules of the compound more amount energy is required to break the hydrogen bond which is present in the primary alcohol
