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

Options

A. `AgNO_(3)(aq)+I_(2)("excess")+H_(2)Orarr" "(p)"Disproportionation"`
B. `K_(2)MnO_(4)(aq)+CO_(2)(g)rarr" "(p)"Comproportionation"`
C. `Na_(2)Cr_(2)O_(7)+C overset(Delta)(rarr)" "(r ) "Redox reaction"`
D. `CuCl_(2)(aq)+Cu(s)rarr" "(s)"One of the products is insoluble in water"`

Answer

A, B, C, D

Explanation

`(A) 5AgNO_(3)(aq)+3overset(0)I_(2)("excess")+3H_(2)O rarr overset(+V)(HlO_(3))+overset(-1)(5Agl)+5HNO_(3)`
disproportionation reaction. AgI insoluble in water.
Redox reaction.
`(B) 3K_(2)overset(+VI)(MnO_(4))(aq)+2CO_(2)(g)rarroverset(+VII)(2KMnO_(4))+overset(+VI)(MnO_(2))+2K_(2)CO_(3)`
disproportionation reaction. `MnO_(2)` insoluble in water. Redox reaction.
`(C ) 2 overset(0)(C)+overset(+VI)(Na_(2)Cr_(2)O_(7))overset(Delta)(rarr)overset(+III)(Cr_(2)O_(3))+overset(+IV)(Na_(2)CO_(3))+overset(+II)(CO)uarr`
Redox reaction. `Cr_(2)O_(3)` ( green pigment) insoluble in water.
