Name the following structure

2–butyne.

Explanation:

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

1. Determine the functional group of the compound.

2. Determine the longest continuous carbon chain. This gives the parent name of the compound.

3. Locate the position of the functional group by giving it the lowest possible count.

4. Combine the above to obtain the name.

Thus, we shall name the compound as follow:

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:

2–butyne
