Question

Correct formula of tetraamminechloronitroplatinum (IV) sulphate can be written as

• A. $[Pt(N{H}_3{)}_4(ONO)Cl]S{O}_4$
• B. $[Pt(N{H}_3{)}_{4}C{l}_{2}N{O}_2{]}_{2}S{O}_4$
• C. $[Pt(N{H}_3{)}_4(N{O}_2)Cl]S{O}_4$
• D. $[PtCl(ONO)N{H}_3(S{O}_4)]$

Answer 1

Answer: (C)

Correct formula of tetraamminechloronitroplatinum (IV) sulphate can be written as
$\left[Pt{\left(N{H}_3\right)}_4\left(N{O}_2\right)Cl\right]S{O}_4$.
Tetraammine represents four ammonia ligands. Only one ammonia ligand is present in the formula for option (D).
Hence, option (D) is ruled out. As per given name, only one chlorine atom should be present.
But two chlorine atoms are present in the formula shown in option (B).
Hence, option (B) is ruled out.
Nitro ligand is represented as $N{O}_2$.
It is not represented as $ONO$.
Hence, option (A) is ruled out.
