Question

Arrange the following in order of decreasing boiling point.

• A. 1> 2 > 3 > 4
• B. 1 > 3 > 4 > 2
• C. 4 > 3 > 2 > 1
• D. 2 > 3 > 1 > 4

Answer 1

Answer: (C)

4 > 3 > 2 > 1

Boiling point increases as the number of carbons is increased.
Boiling point of benzene is least ${80}^{0}C$.
Boiling point of toluene is ${111}^{0}C$.
Boiling point of Mesitylene is ${164}^{0}C$

Boilingpoint of durene is ${192}^{o}C$
