Answer:
The answer is 2-butyne.
Explanation:
Hello!
Let's solve this!
In the attached molecule we see that it has 4 carbons by what is called butane. At the same time we see that it has a triple bond for what belongs to the group of alkynes.
In this case the name is butino (with the ending -ino indicating that it is an alkyne.)
In this case the name is 2-butino because the triple bond is located in the second carbon.
We conclude that the answer is 2-butyne.
