write the IUPAC name and chemical formula of second number of ketones
Answers
Unlike other branches of Chemistry, Organic Chemistry is easily mastered by learning the Functional Groups and Homologous Series of both Aliphatic and Aromatic Compounds. If your question refers to the Ketones of Aliphatic compounds, then as per Homologous Series, the minimum number of carbon atoms required to make the smallest molecule of Ketone is 3. This is due to the fact that Ketones have a carbonyl group (=CO) which is attached to alkyl groups on both sides of the carbonyl carbon atom. The first Aliphatic Ketone is called Acetone or as per IUPAC Nomenclature, Propanone. It’s molecular formula is CH3COCH3 where the =CO group in the middle is called the carbonyl group. Each successive member will be added a -CH2 group ( molecular mass of 14 units) on either side as a general rule; so the 2nd member , Butanone is to have the molecular formula CH3CH2COCH3. It may also be called ethyl methyl ketone.
