Chapter 12, Problem 114AP

Interpretation Introduction

(a)

Interpretation:

The number and arrangement of electron pairs around the indicated atom in the given molecule are to be stated.

Concept Introduction:

The representation an element along with its valence electrons is referred to as Lewis symbol or Electron Dot Symbol. The Lewis structure exhibits the connection between atoms. Each dot around an atom represents electrons.

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

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

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

Generally, the shape of the molecule will be linear if electron pairs are two and the shape of the molecule will be trigonal planar if electron pairs are $3$.
