The IUPAC name of the following compound is,
Options
- A1, 1 - diethyl - 4 - methoxycyclohexane
- B1, 1 - dimethyl - 4 - methoxycyclohexane
- C4, 4 - dimethyl - 1 - methoxycyclohexane
- D4, 4 - Diethyl - 1 - methoxycyclohexane
Correct answer
A. 1, 1 - diethyl - 4 - methoxycyclohexane
Step-by-step solution
The parent ring in the given structure is cyclohexane. The substituents attached to the ring are one methoxy group ( -OCH₃ ) and two ethyl groups ( -CH₂CH₃ ). According to IUPAC nomenclature rules, the ring must be numbered to give the lowest possible set of locants for the substituents. If we start numbering from the carbon with the two ethyl groups, the locant set is 1, 1, 4 . If we start numbering from the carbon with the methoxy group, the locant set is 1, 4, 4 . Comparing the two sets, (1, 1, 4) is lower than
