The alkyne that goes by the common name acetylene has to be identified from the given options. Concept Introduction: IUPAC nomenclature for alkyne: The suffix –ane has to be replaced with the suffix –yne. This is used to indicate the presence of triple bond. The longest continuous chain of carbon atoms has to be chosen that contains both carbon atoms of the triple bond. The parent carbon chain has to be numbered in a way so that the numbering begins at the end near to the triple bond. In case if the triple bond is equidistant from both ends, then numbering has to be done from the end that is closer to substituents. The position of the triple bond has to be given a single number which is lower‑numbered carbon atom that is present in the triple bond. Suffixes like –diyne, -triyne, -tetryne, and so on are used when the compound contains more than one triple bond. Common names for simple alkynes are based on the name acetylene. Acetylene is a two carbon compound which contains a triple bond between the two carbon atoms.

Interpretation Introduction

Interpretation:

The alkyne that goes by the common name acetylene has to be identified from the given options.

Concept Introduction:

IUPAC nomenclature for alkyne:

The suffix –ane has to be replaced with the suffix –yne. This is used to indicate the presence of triple bond.

The longest continuous chain of carbon atoms has to be chosen that contains both carbon atoms of the triple bond.

The parent carbon chain has to be numbered in a way so that the numbering begins at the end near to the triple bond. In case if the triple bond is equidistant from both ends, then numbering has to be done from the end that is closer to substituents.

The position of the triple bond has to be given a single number which is lower‑numbered carbon atom that is present in the triple bond.

Suffixes like –diyne, -triyne, -tetryne, and so on are used when the compound contains more than one triple bond.

Common names for simple alkynes are based on the name acetylene. Acetylene is a two carbon compound which contains a triple bond between the two carbon atoms.
