[Pt(Py)4] [Ptcl4] I.U.P.AC. name
Answers
Answer:
used to produce fibre from plants like jute, flax, hemp stalks, and also coil from coconut husks. The short and long fibres obtained after retting are used widely to manufacture paper, ropes, and wallboards.
Explanation:
[Pt(py)_{4}] [Pt(Cl)_{4}]
IUPAC Name :-
Tetrapyridineplatinum(II) Tetrachloridoplatinate(II)
Explaination :-
In the process of writing IUPAC Name in inorganic chemistry Some rules to be followed
- For IUPAC Name :- For cationic complex = Ligan number + Ligan name + Metal name (In English) + O.N. (oxidation number)
- For anionic complex = Ligan number + Ligan name + Metal name (Latin) + -ate + O.N.
Here,
[Pt(py)_{4}] [Pt(Cl)_{4}]
First complex is cationic complex. So, we write name of first complex with Cationic rule :-
Here,
ligan number = 4
ligan name = pyridine (py)
metal name (English) = platinum
So,
IUPAC name of Cationic complex is
Tetrapyridineplatium()
- Give a bracket for entering O.N.
- we write O.N. in last.
Now,
In Anionic complex :-
ligan number = 4
ligan name = chlorido (CL)
metal name (Latin + -ate) = platinate
So,
IUPAC name of Anionic complex is
Tetrachloridoplatinate()
Calculation of O.N. :-
Let the oxidation number of Pt in cationic complex be x
And
The oxidation number of Pt in anionic complex be y
Now,
→ x + 0×4 + y - 1× 4 = 0 [we know that sum of O.N. in all atoms of a molecule is zero]
→ x + y = 4
Now,
Divide 4 in two equal part
It means 2 and 2.
Now,
Put 2 as oxidation number of Pt in cationic complex.
And
Put 2 as oxidation number of Pt in anionic complex.
In Cationic complex :-
Tetrapyridineplatinum(II)
In Anionic complex :-
Tetrachloridoplatinate(II)
Note :-
The oxidation number is written in Roman number.
