(a)
Interpretation:
The formation of hydrogen bond in terms of electrostatic interactions has to be stated.
Concept introduction:
Electronegativity is defined as the tendency of an atom to attract electrons towards it. Polarized bonds are a result of the electronegativity difference between bonding atoms. The more electronegative atom acquires a partial negative charge and the less electronegative atom acquires a partial positive charge. This results in the formation of the dipole.
(b)
Interpretation:
The formation of hydrogen bond in terms of molecular orbitals has to be stated.
Concept introduction:
Molecular orbital diagrams are used for determining the bonding in molecules using a linear combination of atomic orbitals. The number of molecular orbitals formed is equal to the number of atomic orbitals that combine.
