Step-by-step solution
Structure W: The longest carbon chain containing the phenyl group is a hexane chain. The bromine atoms are at positions 3 and 4. The phenyl group is at position 1. Thus, the name is 3,4-Dibromo-1-phenylhexane. This matches R. Structure X: The benzene ring has a methyl group at position 2, a bromine at position 1, and an isobutyl group at position 4. Following alphabetical order for substituents, the name is 1-Bromo-4-isobutyl-2-methylbenzene. This matches S. Structure Y: The principal functional group is the aldehy
