Chapter 3, Problem 12CTQ

Interpretation Introduction

Interpretation: Lewis structure that corresponds to orbital description shown below should be drawn.

  

Concept introduction: Lewis structures depict covalent bonds and describe valence electrons are present in the molecule.

The sequence that leads to Lewis structure of the molecule is as follows:

• Identify central atom and arrange various other atoms around it. This atom so chosen is the least electronegative one.

• Estimate the total valence electrons.

• Firstly place single bond between each pair.

• The remaining electrons can be allocated lone pairs to satisfy the octet rule for each atom.

Bonds formed due to head-to-head overlap are termed sigma bond while ones formed by sideways or lateral overlap are named pi-bonds.
