ANSWER
1-Butyne
STEP-BY-STEP EXPLANATION:
To name the below structure, we need to consider the following
0. The number of carbon atoms present in the structure
,
1. The type of bond and the location
According to the structure given, we have four carbon atoms
These four carbon atoms mean Butane according to the alkane family
We have a tripple bond in between the first and second carbon atom
Since we have a tripple bond, the -ane in butane will be changed to -yne
Hence, the name of the structure is 1-Butyne
