Chapter 12.9, Problem 12.5SC

Interpretation Introduction

(a)

Interpretation:

The arrangement of electron pairs around the central atom in the given molecule or ion is to be predicted. The sketch and name of the molecular structure for the given molecule or ion are to be stated.

Concept Introduction:

The geometry of the molecule is determined by electron pairs present around the central atom.

The formula to calculate number of electron pairs in compound is,

$\text{Electron}\text{pair}=\text{bond}\text{pair}+\text{lone}\text{pair}$

If electron pairs are $2$ then the shape of molecule is linear.

Similarly, if electron pairs are $3$, then the shape of molecule is trigonal planar.
