What the correct IUPAC name for the compound shown?

Question

Quizplus · Accepted Answer

The compound is a cyclopropane with a methyl and ethyl substituent bonded to the first carbon atom of the cyclopropane ring. The bromine atom is also attached to the same carbon atom. Since the methyl group is closer to the bromine atom than the ethyl group, the name begins with "1-bromo-". The methyl and ethyl groups are then listed in alphabetical order, giving "2-ethyl-1-methyl". Finally, the name ends with "cyclopropane" to indicate the three-carbon ring. Therefore, the correct IUPAC name is 1-bromo-2-ethyl-1-methylcyclopropane.
