The order of boiling points of the following compounds is
1. \(\left(\mathrm{CH}_3\right)_3 \ddot{\mathrm{N}}\)
2. \(\mathrm{CH}_3 \mathrm{CH}_2 \mathrm{CH}_2 \ddot{\mathrm{NH}}_2\)
3. \(\mathrm{CH}_3 \mathrm{CH}_2 \ddot{\mathrm{N}} \mathrm{HCH}_3\)
- A \(1>3>2\)
- B \(3>1>2\)
- C \(2>1>3\)
- D \(2>3>1\)
Answer & Solution
Correct Answer
(D) \(2>3>1\)
Step-by-step Solution
Detailed explanation
Like alkanes dominating inter-molecular force for association of amines to its liquid state is van der Waals' force. We know, \(\text {van der Waals' force } \propto \frac{1}{\text { branching of chain }} \propto \text { boiling point }\) Boiling point
