What is the chemical formula for the aldehyde group?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. -CHO.
The chemical formula for the aldehyde functional group is –CHO. In an aldehyde, the carbon atom is double-bonded to an oxygen atom (forming a carbonyl group) and also bonded to a hydrogen atom. This –CHO group is typically attached to a carbon chain. The general formula for an aldehyde can be written as R–CHO, where "R" represents a hydrocarbon chain or hydrogen atom. Aldehydes are commonly found in various organic compounds and play a significant role in organic chemistry.
