The name of the given molecule according to IUPAC is 1-Butyne. Thus, option C is correct.
<h3>What is IUPAC nomenclature?</h3>
The IUPAC nomenclature is given as the standard naming technique that is used to name a chemical compound. It is named with the following main rules.
The triple bond compound is an alkyne with the suffix -yne. The development of the name to the given structure is therefore given by counting the number of carbon atoms, and the location of the triple bond.
There are 4 carbon atoms in the structure with the triple bond at carbon 1, therefore the name will be 1-Butyne. Hence, option C is correct.
