Final answer:
The complete name of acetylmethylcarbinol is Acetoin, not to be confused with acetone, which is also called propanone or dimethyl ketone. Acetoin has the molecular formula C4H8O2 and differs from acetone (CH3-CO-CH3).
Step-by-step explanation:
The complete name of acetylmethylcarbinol is Acetoin. This compound is a ketone, however, it is distinct from acetone (propanone) which is another common ketone. The naming of ketones typically involves the names of the alkyl groups attached to the carbonyl group followed by the word ketone. The IUPAC name for acetone is propanone, and it is also known as dimethyl ketone. Propanone, being the simplest ketone, consists of two methyl groups around a carbonyl group represented by the formula CH₃-CO-CH₃.
On the other hand, Acetoin is a different molecule with the molecular formula C₄H₈O₂, and it is also known as 3-hydroxybutan-2-one. It differs from acetone in structure and is not to be confused with acetone, acetophenone, acetylacetone or any other ketones.
