Aldehydes Ketones And Carboxylic Acids

To solve the problem, we need to determine how many enolizable hydrogens are present in the compound 2-methylcyclohex-2-en-1-one.

1. Understanding Enolizable Hydrogens:
Enolizable hydrogens are those attached to carbons that are adjacent to a carbonyl group (C=O) or conjugated to a double bond.

2. Analyzing the Structure:
The structure of 2-methylcyclohex-2-en-1-one consists of a cyclohexane ring with a methyl group at position 2, a double bond at position 2, and a ketone group at position 1.

3. Identifying Enolizable Hydrogens:
The hydrogens at the following positions are enolizable:
- The hydrogen attached to carbon 3 (adjacent to the carbonyl group).
- The hydrogens attached to the carbons conjugated to the double bond at position 2.

4. Conclusion:
There are a total of 4 enolizable hydrogens in the compound 2-methylcyclohex-2-en-1-one.

Final Answer:
The compound contains 4 enolizable hydrogens.

The common name "acetone" refers to the ketone known as dimethyl ketone. Acetone is the simplest and most well-known ketone, with the chemical formula (CH₃)₂CO. It consists of a central carbonyl group (C=O) bonded to two methyl groups (CH₃). Among the given options, dimethyl ketone directly matches the structure and traditional naming associated with acetone. Hence, the correct option is dimethyl ketone.
