Answer: The molecular formula for a ketone is C3H6O.
CH3–C = O–CH3 is the most basic ketone. C3H6O is its molecular formula. We can deduce from this formula that “n” carbon atoms require “ 2n ” hydrogen atoms and an oxygen atom. As a result, the usual formula for ketone is CnH2nO.
The carboxyl group in the keto group has two alkyl groups connected to it on either side. R–C = O–R is the structural formula.
Aldehydes and ketones are organic compounds with a carbonyl C = O functional group.
