00:01
For option a.
00:04
In the given compound, oxidation state of carbonate iron is negative 2, and the oxidation state of co is assumed as x.
00:16
So, solving the equation, the oxidation state, oxidation number of co turns out to be plus 3.
00:23
According to nomenclature rule, the ligand is named first, followed by the central metal in a complex.
00:30
Central metal is co, as the complex is an anion, therefore, name of the complex will be tricarbonate, cobaltate, 3 -ion.
00:43
For option b, cu is linked with 4 amine molecules.
00:49
The oxidation state of ammonia is 0.
00:52
The oxidation state of cu is assumed to be x.
00:56
Solving for the oxidation state, the oxidation number of cu is plus 2.
01:03
We know the nomenclature rule.
01:05
The central metal co is linked to 4 -amine molecule.
01:09
The complex is cation.
01:11
Therefore, name of the complex will be tetraamine copper 2 -ion.
01:17
For option c, in a complex, oxidation state of ammonia is 0, of bromine is minus 1, and sulfate ion is negative 2.
01:29
The oxidation state of co is assumed to be x.
01:33
So, the oxidation number of co is plus 5.
01:37
According to the nomenclature rule, the ligand is named first followed by the central metal.
01:44
The central metal is co, linked with four ammonia molecules and two bromide ions.
01:51
The complex therefore named as tetraamine dibromo cobalt 3 sulfate.
01:59
For option d, the oxidation state of ammonia is zero to that of chlorine is negative 1.
02:05
Consider pt as x.
02:08
The oxidation number of pt turns out to be plus 2.
02:11
Through the nomenclature rule, the pt is central atom linked to 4 ammonia molecules with 4 chloride ions...
