question
which of the following is the formula for the simplest ketone?
select the correct answer below:
○ ch₃coh
○ ch₃ch₂cho
○ ch₃coch₃
○ hcho

Explanation:

Step1: Understand ketone structure

A ketone has the general formula \( R - CO - R' \), where \( R \) and \( R' \) are alkyl groups.

Step2: Analyze each option

• \( \text{CH}_3\text{COH} \): Incorrect structure (not a valid ketone formula).
• \( \text{CH}_3\text{CH}_2\text{CHO} \): This is an aldehyde (\( -CHO \) group).
• \( \text{CH}_3\text{COCH}_3 \): Follows the ketone formula (\( R - CO - R' \), here \( R = R'=\text{CH}_3 \)).
• \( \text{HCHO} \): This is formaldehyde, an aldehyde.

Answer:

C. \( \text{CH}_3\text{COCH}_3 \)
