💡 Solution & Explanation

Step 1 - Identify the parent chain/ring: The structure shows a cyclohexane ring, which serves as the parent cyclic structure. Step 2 - Identify the principal functional group: There is a -C(=O)-O-CH3 (methoxycarbonyl / ester) group directly attached to the cyclohexane ring. When a -COOH (or its ester) is directly attached to a ring, the ring carbon bearing the carboxyl group is C1, and the compound is named as a cyclohexanecarboxylic acid derivative. Since the acid portion is esterified with methanol (-OCH3), the parent name is methyl cyclohexanecarboxylate. Step 3 - Identify substituents: A bromine (Br) atom is attached to the ring carbon adjacent to C1, i.e., at C2. Step 4 - Number and name: The ester carbon at C1 gives the lowest locant to the principal group. The bromine at the next carbon is therefore at position 2. The full IUPAC name is methyl 2-bromocyclohexane-1-carboxylate, commonly written as methyl-2-bromocyclohexane carboxylate. Step 5 - No other options are provided to eliminate; the structure unambiguously corresponds to a cyclohexane ring bearing a -COOMe group at C1 and Br at C2. Therefore, the correct answer is methyl-2-bromocyclohexane carboxylate.
