Question

Assertion: Butan-2-ol has higher boiling point than 2-methylpropan-2-ol. Reason: Amongst isomeric alcohols, the boiling points decreases with branching.

Answer 1

Answer:

maybe A is correct but R is not correct explanation of A

Explanation:

n-butanol and 2-methyl propan-2-ol. Butanol has the higher boiling point as the branching increases the surface area of the molecule decreases so the boiling point decreases.

I hope it's helpful to you!!

Answer 2

Answer:

Both the statements are true and reason is the correct explanation of assertion.

Explanation:

Boiling point is the point at which liquid changes into gas at atmospheric temperature.

Various factors affect boiling points like  temperature, atmospheric pressure, and the vapor pressure of the liquid and one is the branching of chains as branching increases boiling point decreases.
