Assertion: Hydrogen bonding is responsible for the unique properties of water, such as its high boiling point and density.
Reason: Hydrogen bonding is a type of intermolecular force that occurs between molecules containing polar covalent bonds, resulting in strong attractive forces.
Reason: Hydrogen bonding is a type of intermolecular force that occurs between molecules containing polar covalent bonds, resulting in strong attractive forces.
View answer and explanation
Correct option: B
Both Assertion and Reason are true, but Reason is not the correct explanation for Assertion
Option A is correct because both statements are correct, and Statement II correctly explains Statement I. Exothermic reactions can become spontaneous at low temperatures due to the decrease in entropy's influence.
