Concept explainers
Provide the IUPAC name for each of the following

Interpretation:
IUPAC names for the given structures of alkyne are to be written.
Concept introduction:
The presence of a triple bond in a structure represents that the hydrocarbon is an alkyne.
To determine the name of the parent alkyne, select the longest continuous carbon chain containing the carbon‐carbon triple bond.
The parent name of the alkyne comes from the IUPAC name for the alkane having the same number of carbon atoms.
The numbers are assigned to the carbon atoms in the parent chain from the end which gives the lowest number to the substituents.
The name of any substituent atom or group and its location is indicated.
Name of substituent present in the structure is written before the name of the parent chain.
