The correct Answer is:

Hydroquinone acts as developer
(Q) `BaCl_(2)+K_(2)Cr_(2)O_(7)+3H_(2)SO_(4)toK_(2)SO_(4)+2CrO_(2)Cl_(2)+2BaSO_(4)+3H_(2)O` ltbr. (R) `FeSO_(4)+K_(3)[Fe(CN)_(6)]toKF e^(II)[Fe^(III)(CN)_(6)]+K_(2)SO_(4)`
(S) `Co(NO_(3))_(2)+ZnOoverset(Delta)toCoZnO_(2)` or CoO. ZnO

Match the reactions in Column I with nature of the reactions/type of the products in Column II

`{:(A,B,C,D),(2,1","4,3,4):}`

`{:(A,B,C,D),(1","4,3,1","2,1):}`

`{:(A,B,C,D),(2,3,1,4):}`

`{:(A,B,C,D),(3,4,2","3,1):}`

Match the reactions in Column I with nature of the reactions / type of the products in Column II

`{:(,"Column I",,"Column II"),((A), O_(2)^(-) rarr O_(2) +O_(2)^(2-) ,(P), "Redox reaction"):}`

`{:(,"Column I",,"Column II"),((B) , CrO_(4)^(2-) + H^(+) rarr, ( Q) , "One of the products has trigonal planar structure "):}`

`{:(,"Column I",,"Column II"),((C ) ,MnO_(4)^(-)+NO_(2)^(_) +H^(+) rarr , ( R ) , "dimeric bridged tetrahedral metal ion"):}`

`{:(,"Column I",,"Column II"),((D) , NO_(3)^(-) + H_(2)SO_(4) + Fe^(2+) rarr, ( S )," disproportionation"):}`

Match the reactions in Column I with nature of the reactions // type of the products in Column II.

`O_(2)^(-)rarrO_(2)+O_(2)^(2)" "(p)` redox reaction

`CrO_(4)^(2-)+H^(+)rarr" "(q)` One of the products has trigonal planar structure

`MnO_(4)^(-)+NO_(2)^(-)+H^(+)rarr" "(r )` dimeric bridged tetrahdedral metal ion

`NO_(3)^(-)+H_(2)SO_(4)+Fe^(2+)rarr" "(s)` disproportionation
