Question

Would increased intermolecular hydrogen bonding lead to a higher or lower melting point? Explain.

Answer 1

Intermolecular hydrogen bonding increases the boiling point of substance because the molecule form long chain by the help of hydrogen bond which increases the exposed surface area of molecule and increase the lateral branching. And as the lateral branching increases the molecule becomes strengthen and boiling point increases. While in case of intramolecular hydrogen bonding. the molecule become compact and the exposed surface area decreases so the boiling point decreases
