Arrange the following in decreasing order of their boiling points.
Options
- AA>B>D>C
- BA>C>D>B
- CB>C>D>A
- DC>A>B>D
Correct answer
A. A>B>D>C
Step-by-step solution
The boiling point of ( A ) alcohol is highest due to H -bonding. Out of primary (B), secondary (D) and tertiary amines (C), the boiling point in decreasing order is Primary amine > Secondary amine > Tertiary amine as intermolecular association decreases in same order, being highest in primary amine and least in tertiary amine due to steric hindrance. The correct decreasing order of boiling point in given compound is A > B > D > C.
