Question

Name the compound

ScanSolve AI Tutor · Accepted Answer

To name the compound, we follow the IUPAC nomenclature rules for ketones.

Identify the longest continuous carbon chain containing the ketone functional group.
The longest chain containing the carbonyl group ( $\text{C}=\text{O}$ ) has six carbon atoms. This makes the parent alkane "hexane".
Number the carbon chain to give the ketone functional group the lowest possible number.
If we number from left to right, the ketone is at carbon 3.
If we number from right to left, the ketone is at carbon 4.
Therefore, we number from left to right, placing the ketone at position 3. The parent name becomes "hexan-3-one".
Identify and name any substituents and their positions.
- At carbon 2, there is a methyl group ( $\text{CH}_3$ ).
- At carbon 4, there is an ethyl group ( $\text{CH}_2\text{CH}_3$ ).
Assemble the full name, listing substituents in alphabetical order.
Ethyl comes before methyl alphabetically.
So, the name is 4-ethyl-2-methylhexan-3-one.

The name of the compound is $\text{4-ethyl-2-methylhexan-3-one}$ .
