A) (A) - (ii); (B) - (i); (C) - (iii)
B) (A) - (iii); (B) - (ii); (B) - (i)
C) (A) - (ii); (B) - (iii); (C) - (i)
D) (A) - (iii); (B) - (i); (C) - (ii)
Correct Answer: B
Solution :
(a) (b) (c) \[\underset{\text{Thiourea}}{\mathop{N{{H}_{2}}-\underset{C}{\overset{S}{\mathop{||}}}\,-N{{H}_{2}}}}\,\xrightarrow[{}]{Na}NaSCN\xrightarrow[{}]{FeC{{l}_{3}}}\underset{\text{Red}\,\text{colour}}{\mathop{F{{e}_{4}}{{\left[ Fe{{\left( SCN \right)}_{6}} \right]}_{3}}}}\,\]You need to login to perform this action.
