8 Commenti
Guida verificata passo dopo passo1
Identify the parent compound: The structure is based on acetophenone, which is a benzene ring with an acetyl group (C=OCH3) attached.
Determine the position of the acetyl group: The acetyl group is typically given the highest priority and is assigned position 1 on the benzene ring.
Identify and number the substituents: There are two substituents on the benzene ring - a cyclohexyl group and an ethyl group. Number the ring to give the lowest possible numbers to these substituents.
Assign numbers to the substituents: The cyclohexyl group is attached to position 4, and the ethyl group is attached to position 3, based on the lowest numbering rule.
Combine the names: The correct IUPAC name is formed by listing the substituents in alphabetical order followed by the parent compound. Thus, the name is 4-cyclohexyl-3-ethyl-1-acetophenone.
