Question

3. Arrange the following compounds in increasing order of their melting points; 1-Bromobutane, 2-Bromobutane and 2-Bromo-2-methylpropane

Answer 1

Answer:

2-Bromo-2-methylpropane < 2-Bromobutane < 1 - Bromobutane

Explanation:

For isomeric halides, as the number of branches increases, surface area of the molecule decrease which decreases the force of attraction. Therefore melting & boiling point decreases.
