Chapter 18, Problem 35E

Interpretation Introduction

Interpretation:

Each compound is to be determined as an alkane, alkene, or alkyne on the basis of their molecular formula.

Concept introduction:

In organic chemistry, alkanes are the compounds that are saturated and contain $\text{C-C}$ bonds (carbon-carbon). The molecular formula of an alkane is ${\text{C}}_{\text{n}}{\text{H}}_{\text{2n+2}}$.

Alkenes are the compounds that are unsaturated and have at least one double bond between carbons ($\text{C=C}$). The molecular formula of an alkyne is ${\text{C}}_{\text{n}}{\text{H}}_{\text{2n-2}}$.

Alkynes are the compounds that have at least one triple bond ($\text{C}\equiv \text{C}$). The molecular formula of an alkyne is ${\text{C}}_{\text{n}}{\text{H}}_{\text{2n-2}}$.
