Isomeric amines with molecular formula $\displaystyle \mathrm{C}_8 \mathrm{H}_{11} \mathrm{~N}$ give the following tests Isomer (P) ⇒ Can be prepared by Gabriel phthalimide synthesis Isomer (Q) ⇒ Reacts with Hinsberg's reagent to give solid insoluble in NaOH Isomer $\displaystyle (\mathrm{R}) \Rightarrow$ Reacts with HONO followed by $\displaystyle \beta$ - naphthol in NaOH to give red dye. Isomers (P), (Q) and (R) respectively are $\displaystyle \mathrm{P} \qquad \mathrm{Q} \qquad \mathrm{R}$
