Chapter 7, Problem 75QAP
Interpretation Introduction

(a)

Interpretation:

The formula of the ion or molecule in which an atom of N forms 3 bonds using sp3 hybrid orbitals needs to be determined.

Concept introduction:

  • Hybridization involves mixing of valence orbitals to form new orbitals that are lower in energy and more stable than the original orbitals. The new orbitals are termed as hybrid orbitals.
  • The molecular geometry can be predicted by classifying the species type as: AXm En ,
  • A = central atom; X = atom bonded to the central atom; E = lone pairs on the central atom

    m = number of atoms around the central atom or the number of bonds around A

    n = number of unshared electron pairs.

    The value of m + n reflects the geometry and hybridization of the central atom

Interpretation Introduction

(b)

Interpretation:
