Chapter 8, Problem 84A

(a)

Interpretation Introduction

Interpretation:

Sigma and pi bond of the following molecule needs to be explained.

Concept introduction:

Nonionic compounds share electrons. The bond which results from the formation of electron sharing is termed as covalent bond. In this bonding, the shared pair of electrons is taken from the outermost energy level.

Answer to Problem 84A

Sigma and pi bond of the given molecule is as follows:

Explanation of Solution

Sigma bonds are the single covalent bond. Multiple covalent bond consist of both pi and sigma bond. Double bond comprises of one sigma bond and pi bond. A triple bond comprises of two pi bond and one sigma bond. The given molecule contains three sigma bonds and one pi bond.
