Chapter 1, Problem 73P

(a)

Interpretation Introduction

Interpretation:

Lewis structure for ${\text{CH}}_{\text{3}}{\text{N}}_{\text{2}}{}^{\text{+}}$ should be drawn.

Concept introduction:

Lewis structure:

A structure that shows the bonding between atoms of a molecule and lone pair of electron that may present in the molecule is called as Lewis structure.

• The bond angel depends on the orbital used by Carbon to form the bond.
• The greater the amount of s characters in the orbital, the larger the bond angel.
• For example, ${\text{sp}}^3$ carbon have bond angel of ${109.5}^0$, ${\text{sp}}^2$ carbon have bond angel of ${\text{120}}^{\text{0}}$, and $\text{sp}$ carbon have bond angel of ${\text{180}}^{\text{0}}$.
• Lone-pair electrons are valence electrons that are not used in bonding.
• Lewis structure indicates which atom is bonded together and show lone pairs and formal charge.
