Chapter 4, Problem 53E, Indigo is the dye used in coloring blue jeans. The term navy blue is derived from the use of indigo

a. How many σ bonds and π bonds exist in the molecule?

b. What hybrid orbitals are used by the carbon atoms in the indigo molecule?

(a)

Interpretation Introduction

Interpretation: The structure of an indigo molecule has been given. Based on the structure, the stated questions have to be answered.

Concept introduction: The hybridization of an atom can be obtained by finding its steric number. The sum of the numbers of atoms bonded to the required atom and the number of lone pairs the atom has is known as the steric number.

If the steric number is 4 , the atom is sp3 hybridized.

If the steric number is 3 , the atom is sp2 hybridized.

If the steric number is 2 , the atom is sp hybridized.

Sigma bonds are the single bonds present between atoms in a compound. The second bonding that occurs between the atoms is known as the pi bonding.

To determine: The number of σ bonds and the number of π bonds present in the given structure.

Explanation of Solution

The single bonds present in the molecular structure are known as σ bonds, whereas the second bond that occurs between atoms is referred to as a π bond.

A double bond is made up of one σ bond and one π bond.

The given structure of the compound is,

(b)
