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:
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:
- Both A and R are true and R is the correct explanation of A
- A is true but R is false
- Both A and R are true but R is not the correct explanation of A
- A is false but R is true
The Correct Option is A
Solution and Explanation
Butan-1-ol contains an -OH group, allowing it to form hydrogen bonds, which increase intermolecular forces and raise the boiling point.
Ethoxyethane (ether) cannot form hydrogen bonds due to the lack of an -OH group, resulting in weaker intermolecular forces and a lower boiling point.
Hydrogen bonding is the primary reason for the stronger association of molecules in butan-1-ol compared to ethoxyethane.
Thus, both A and R are true, and R is the correct explanation of A.
