Given below are two statements : One is labelled as Assertion A and the other is labelled as Reason R.

Assertion A : Butan–1–ol has higher boiling point than ethoxyethane.

Reason R : Extensive hydrogen bonding leads to stronger association of molecules.

In the light of the above statements, choose the correct answer from the options given below :

Options:

Answer:
B
Solution:

Butan-1-ol can undergo hydrogen bonding due to the presence of an -OH group, ethoxyethane (also known as diethyl ether) can also participate in hydrogen bonding.

Even though there are no hydrogen atoms directly bonded to a highly electronegative atom (like F, O, or N) in ethoxyethane, the molecule still has polar C-O bonds that can lead to dipole-dipole interactions with other polar molecules.

Owing to intermolecular hydrogen bonding in butanol, it has higher boiling point than ethoxyethane.
