Paraphin [41]

Answer:

2–butyne.

Explanation:

To name the compound given above, we must determine the following:

1. Determine the functional group of the compound.

1. The compound contains triple bond (C≡C). Therefore, the compound is an alkyne.

2. The longest chain is carbon 4. Thus the parent is butyne.

3. The triple bond (C≡C) is located at carbon 2 when we count from either side.

4. The name of the compound is:
