Match the complex in Column I with the isomerism it can show in Column II. Column I: P [Co(NH3)5Cl]SO4; Q [Cr(H2O)6]Cl3; R [Co(NH3)5(NO2)]Cl2; S [Cu(NH3)4][PtCl4]. Column II: (1) hydrate; (2) coordination; (3) linkage; (4) ionisation.

Match the complex in Column I with the isomerism it can show in Column II. Column I: P $[Co (NH X_{3}) X_{5} Cl] SO X_{4}$ ; Q $[Cr (H X_{2} O) X_{6}] Cl X_{3}$ ; R $[Co (NH X_{3}) X_{5} (NO X_{2})] Cl X_{2}$ ; S $[Cu (NH X_{3}) X_{4}] [PtCl X_{4}]$ . Column II: (1) hydrate; (2) coordination; (3) linkage; (4) ionisation.

P exchanges

Cl X^{-}

and

SO X_{4} X^{2 -}

with the counter ion to give

[Co (NH X_{3}) X_{5} SO X_{4}] Cl

: ionisation. Q can swap water and chloride between sphere and lattice: hydrate. R has ambidentate

NO X_{2} X^{-}

: linkage. S is a salt of two complex ions that can exchange ligands: coordination. So P-4, Q-1, R-3, S-2.
