Propose a structure for an aromatic hydrocarbon, C9H12, that can form only one C9H11Br product on substitution of a hydrogen on the aromatic ring with bromine. You do not have to consider stereochemistry. In cases where there is more than one answer, just give one. Ignore the ortho, para-directing effects of the alkyl groups in answering this question. Consider only the number of nonequivalent hydrogens on the aromatic ring. ChemDoodle®

Question (1): Find the area bounded by the graphs of $y = x^2$ and $y = 8 - x^2$ for $0 \le x \le 8$. $x^2 = 8 - x^2$ $2x^2 = 8$ $\frac{2x^2}{2} = \frac{8}{2}$ $x^2 = 4$ $\sqrt{x^2} = \sqrt{4}$ $x = \pm 2$ $x = 2$ only take $x = 2$ because $-2$ is not in the domain $x = 2$ $A = \int_0^2 [8 - x^2 - (x^2)] dx + \int_2^8 [x^2 - (8 - x^2)] dx$ $= \int_0^2 (8 - 2x^2) dx + \int_2^8 (2x^2 - 8) dx$ $= \frac{32}{3} + \frac{288}{3} - \frac{84}{3}$
