Interpretation Introduction

Interpretation:

The isomeric alkynes having molecular formula ${\text{C}}_{\text{5}}{\text{H}}_{\text{8}}$ are to be described in terms of structural formula, chirality, and stereoisomerism.

Concept introduction:

Alkynes are hydrocarbons having carbon–carbon triple bonds.

Molecule ${\text{C}}_{\text{5}}{\text{H}}_{\text{8}}$ has three different isomeric structures, but the molecular formula would be the same.

The structural formula of a chemical compound consists of graphical representation of the molecular structure and the arrangement of atoms.

Stereoisomers are isomeric moleculeshaving same molecular formula and bonding sequence of atoms but different spatial arrangement.

When C atom is attached to four different groups, it is called the chiral carbon. A chiral molecule is non-superimposable on its mirror image.
