Answer : A Ketone is an organic compound in which a carbonyl group is bonded to two different carbon atoms.
Explanation :
A Ketone is an organic compound having a structure
where R and R' can be different carbon containing substituents.
Ketone is a compound in which the a carbonyl group is bonded to the two different carbon atoms which are R and R' and there is a double bond present between the carbon and oxygen atom.
Some examples of ketones are, acetone, propanone, butanone, etc.
Hence, a Ketone is an organic compound in which a carbonyl group is bonded to two different carbon atoms.
