Answer 1

pentanone is the IUPAC name

Answer 2

IUPAC name of $CH_3-CH_2-CO-CH_2-CH_3$ is 3-Pentanone.

Explanation:

• To write the IUPAC name of a compound, the following things must be first identified they are:

1. Substituents whose name must be written as prefix of the compound.
2. Number of carbons
3. Nature of bond
4. Functional group whose name must be written as suffix of the compound.

• Accordingly, when the given structure is examined, it gives the following details:

1. No substituents group is present.
2. There are 5 carbon atoms present in the chain. Thus the root word is -Pent.
3. Since all the carbon has single bond, the nature of bond is -ane.
4. The functional group attached is '-CO' which is a ketone. Thus the suffix is -one.
5. While numbering, the numbering should be done in such a way that the main functional group gets the lowest number.
6. In the given case, the main functional group is -CO. As it is present in the center, the numbering can be started from any side.

• Thus the IUPAC name of $CH_3-CH_2-CO-CH_2-CH_3$ is 3-Pentanone.
