Isomeric amines with molecular formula C$$_8$$H$$_{11}$$N give the following tests
Isomer (P) $$\Rightarrow$$ Can be prepared by Gabriel phthalimide synthesis
Isomer (Q) $$\Rightarrow$$ Reacts with Hinsberg's reagent to give solid insoluble in NaOH
Isomer (R) $$\Rightarrow$$ Reacts with HONO followed by $$\beta$$-naphthol in NaOH to give red dye.
Isomers (P), (Q) and (R) respectively are
Given below are two statements:
Statement I : Aqueous solution of K$$_2$$Cr$$_2$$O$$_7$$ is preferred as a primary standard in volumetric analysis over Na$$_2$$Cr$$_2$$O$$_7$$ aqueous solution.
Statement II : K$$_2$$Cr$$_2$$O$$_7$$ has a higher solubility in water than Na$$_2$$Cr$$_2$$O$$_7$$.
