Question

The order of boiling point of primary (1), secondary (2) and tertiary (3) alcohols is:

• A. 1 > 2 > 3
• B. 3 > 2 > 1
• C. 2 > 1 > 3
• D. 2 > 3 > 1

Answer 1

The correct option is A 1 > 2 > 3

The order of the boiling point is $Primary\left(1\right)>secondary\left(2\right)>tertiary\left(3\right)alcohol$

This is because the surface area decreases and the van Der waals forces decreases.
