Solution

(A) The reaction $F e (S C N)_{3} + K F (a q) e x c e s s$ gives dimagnetic product.
(B)The reaction $C r O_{2} C l_{2} + N a O H (a q)$ produce coloured product (s). The product is dimagnetic with tetrahedral geometry around metal.
(C) The reaction $N i^{+ 2} + d m g C H_{3} C O O H - ------- \to C H_{3}^{+} C O O N a$ produce coloured product (s). The product is dimagnetic product. It is hydrogen bonded product.
(D)The reaction $N a_{2} S O_{3} + C r_{2} O_{7}^{- 2}^{+}$ produce coloured product (s).
The product is diamagnetic. It has tetrahedral geometry around metal.
