Question

Quizplus · Accepted Answer

The longest chain of carbons in the molecule is three, forming a cyclopropane ring. The bromine atom is attached to the first carbon atom and the ethyl and methyl groups are attached to the second carbon atom. There are two possible ways of numbering the carbon atoms in the ring, but the lowest possible number is assigned to the bromine atom. Therefore, the correct IUPAC name is 1-bromo-2-ethyl-1-methylcyclopropane.
