Organic Chemistry, Chapter 15.SE, Problem 23AP , additional homework tip 1

Explanation of Solution

The molecular formula of the compound is C₉H₁₂. Benzene ring accounts for six carbons. When the three carbons remaining are arranged as three methyl groups alternatively on the benzene ring the three hydrogens on the other three carbons become equivalent. Hence upon bromination, the hydrocarbon gives only one monosubstituted product.
