Chapter 7.3A, Problem 7.2P

Interpretation Introduction

Interpretation: The number of elements of unsaturation implied by the molecular formula ${\text{C}}_4{\text{H}}_6$ is to be calculated and nine structure of the compound that the molecular formula ${\text{C}}_4{\text{H}}_6$ are to be represented.

Concept introduction: The compounds that have double bond or triple bond are called unsaturated compounds.

The compounds having same molecular formula and different structural arrangement of the atoms are called isomers of that compound. Isomers are of two types; structural isomers and stereoisomer. The Structural isomers can be chain isomer, position isomer and functional group isomers.

To determine: The number of elements of unsaturation implied by the molecular formula ${\text{C}}_4{\text{H}}_6$ and nine structures of the compound that have the molecular formula ${\text{C}}_4{\text{H}}_6$.
