Chapter 14, Problem 14B.4DQ

(a)

Interpretation Introduction

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 Introduction

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.
