Which of the following compounds is an aldehyde?

Correct Answer: CH3CHO

Step 1: Understand what an aldehyde is. An aldehyde is a type of organic compound that contains a functional group called -CHO.
Step 2: Identify the structure of the compound CH3CHO. It consists of a carbon (C) atom bonded to a hydrogen (H) atom and a carbonyl group (C=O).
Step 3: Check if the compound has the -CHO functional group. In CH3CHO, the -CHO group is present, confirming it is an aldehyde.
Step 4: Compare CH3CHO with other compounds (if provided) to see if they have the -CHO group. Only the compound with this group is an aldehyde.
