(a)
Interpretation:
Give reason for the lower boiling point of
Concept Introduction :
Boiling and melting points of molecular substances depend upon the strength of the intermolecular forces involved. The stronger the intermolecular forces, the higher will be the boiling and melting point of the substance. This is so because more energy is required to overcome strong bonds, whereas less energy is required to overcome weak bonds.

Interpretation:
Give reason for the higher boiling point of

(c)
Interpretation:
Give reason for the lower boiling point of formic acid than benzoic acid, on the basis of structural units.
