1.

Arrange the following compounds in increasing order of boiling point : Propan-1-ol, butan-1-ol, butan-2-ol, pentan-1-olA. Propan-1-ol `lt` butan-2-l `lt` butan-1-pl `lt` pentan-1-olB. Propan-1-ol `lt` butan-1-ol `lt` butan-2-ol `lt` pentan-1-olC. Pentan-1-ol `lt` butan-2-ol `lt` butan-1-ol `lt` propan-1-olD. Pentan-1-ol `lt` butan-1-ol `lt` butan-2-ol `lt` propan-1-ol

Answer» Correct Answer - A
With the increase in molecular mass, the boiling points also increase. Amongest isomeric alcohols, the boiling point decreases with branching due to decrease in surface area.
