Chapter 13, Problem 13.88EP

Interpretation Introduction

Interpretation:

The general formula for a cycloalkyne that contain one carbon‑carbon triple bond has to be given.

Concept Introduction:

Hydrocarbons are the organic compounds that contain only hydrogen and carbon atoms. Hydrocarbon derivatives are the one in which the compounds contain hydrogen and carbon atoms along with one or more additional elements. The additional elements that can be present in hydrocarbon derivatives are oxygen, nitrogen, sulphur, chlorine, bromine etc.

Hydrocarbons are further classified into two categories. They are saturated hydrocarbons and unsaturated hydrocarbons. The hydrocarbons that contain single bonds between carbon atoms in the entire molecule is known as saturated hydrocarbon. The hydrocarbons that contain atleast one double or triple bond between two carbon atoms in the entire molecule is known as unsaturated hydrocarbon.

Alkynes are a class of unsaturated hydrocarbons. These will have at least one triple bond between two carbon atoms. An alkyne is an acyclic unsaturated hydrocarbon. The functional group of alkyne is $\text{C}\equiv \text{C}$. The general formula of alkyne with one triple bond is ${\text{C}}_{\text{n}}{\text{H}}_{\text{2n-2}}$.

Cycloalkynes with one triple bond has a general molecular formula of ${\text{C}}_{\text{n}}{\text{H}}_{\text{2}}{}_{\text{n-4}}$. This is a cyclic unsaturated hydrocarbon.
