Chapter 4, Problem 2CHQ

(a)

Interpretation Introduction

Interpretation: The three-dimensional shape and Lewis structure of should be determined

Concept Introduction:

• VSEPR theory: This theory was developed to predict the shapes of covalent molecules in which atoms are joined together with single covalent bond. According to this theory

• The electron pairs around the central atom in a molecule tend to stay in space as far as possible so that repulsive forces between electron pairs are minimum
• The geometry or shape of the molecule is determined by the orientation of electron pairs.
• The shape of the molecule is regular if the electron pairs around the central atom are shared pairs only because they exert repulsive forces equally
• The shape are irregular if they have shared as well as lone pair around the central atom because they exert repulsive forces unequally.

• Lewis dot structure: The structure which shows the distribution valance electrons of all the atoms involved in bonding. This includes bonding electrons as well as lone pair of electrons.
