Answer: Follow me
ACETONE
Because the carbonyl group in a ketone must be attached to two carbon groups, the simplest ketone has three carbon atoms. It is widely known as acetone, a unique name unrelated to other common names for ketones.
Propanone
The first member of Ketones is (IUPAC name) 2 - propanone. H3C - CO - CH3. This is also called Acetone. Ketone series of Organic compounds have the group CO in them between two groups that contain Carbon.
Answer:The name acetone is related to other common names.
Explanation:The common name acetone is related to other common names. acet- is the common term used for 2 carbons joined. Acetaldehyde has 1 methyl group and 1 carbonyl group for 2 carbons and a hydrogen to create an aldehyde. Acetic acid has the same 2 carbons as acetaldehyde but the hydrogen is replaced with a hydroxy group making it an organic acid. Acetone has the same 2 carbons as acetaldehyde and acetic acid giving it the acet- prefix, but the hydrogen and hydroxy groups respectively are replace with a methyl group making it a ketone.
