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 :

1. A is true but R is false
2. Both A and R are true and R is the correct explanation of A
3. Both A and R are true but R is not the correct explanation of A
4. A is false but R is true

Correct answer: Both A and R are true and R is the correct explanation of A

Solution

Butan-1-ol has a higher boiling point than ethoxyethane due to its ability to form extensive hydrogen bonds, which results in stronger intermolecular forces compared to the weaker van der Waals forces present in ethoxyethane.
