Chapter 14, Problem 72AE

(a)

Interpretation Introduction

Interpretation: The molecular structure from given resonance structures needs to be determined.

  

Concept Introduction:

Lewis dot structure is the representation which shows the bonding between atoms present in a molecule. It shows lone pairs and bond pairs that existing on each bonded atom. Lewis dot structure is also known as Lewis dot formula or electron dot structure.

The sum of valence electrons must be arranged in such a way that all atoms must get octet configuration (8 electrons).

  $\text{Hybridization = Number of sigma bonds + Number of lone pairs on bonded atoms}\text{.}$

Resonance is the phenomenon of interaction of pi bond and lone pairs of electrons to stabilize the given molecule.

(b)

Interpretation Introduction

Interpretation: The hybridization of P in both the given structures needs to be determined.
