Chapter 7.3A, Problem 7.1P

(a)

Interpretation Introduction

To determine: The number of hydrogen atoms in the hydrocarbon that has nine carbon atoms, three double bonds and one ring.

Interpretation: The number of hydrogen atoms in the hydrocarbon that has nine carbon atoms, three double bonds and one ring is to be calculated.

Concept introduction: The compounds that have double bonds or triple bonds are called unsaturated compounds. Alkenes are the unsaturated compounds that have double the number of hydrogen atoms than the number of carbon atoms.

(b)

Interpretation Introduction

To determine: The number of elements of unsaturation implied by the molecular formula ${\text{C}}_{\text{6}}{\text{H}}_{\text{12}}$.

Interpretation: The number of elements of unsaturation implied by the molecular formula ${\text{C}}_{\text{6}}{\text{H}}_{\text{12}}$ is to be calculated.

Concept introduction: The compounds that have double bond or triple bond are called unsaturated compounds. Alkenes are the unsaturated compounds that have double number of hydrogen atoms than the number of carbon atoms.

(c)

Interpretation Introduction

To determine: The five structures of the compound that have the molecular formula ${\text{C}}_{\text{6}}{\text{H}}_{\text{12}}$, atleast one of them containing a ring and another one containing a double bond.

Interpretation: The five structures of the compound that have the molecular formula ${\text{C}}_{\text{6}}{\text{H}}_{\text{12}}$, atleast one of them containing a ring and another one containing a double bond are to be drawn.

Concept introduction: The structure of the compound is the graphic representation of the molecular formula that shows that the arrangement of the atoms in the compound.

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.
