coordination number depends on the no. of ligands attach to the central metal in the coordination sphere. so, 6 is correct answer hope it helps you, comment if any query.
Similarly, How many isomers are possible for CO NH3 3Cl3?
(ii) Two isomers are possible for [Co(NH3)3Cl3] Note. 1, 2, 3,-position is called cis isomer while position 1, 2, 6 is called as trans isomer.
Additionally, What is the coordination number of NH3? The NH3 ligand is neutral, but the chloro ligand has a charge of 1−. The oxidation state is found by +2 = −1 + x and is 3+, so the complex is pentaaminechlorocobalt(III) chloride and the coordination number is six.
How do you find the coordination number?
Here are the steps for identifying the coordination number of a coordination compound.

How many isomers are there of the octahedral coordination complex co NH3 3cl3?
[Co(NH3)3Cl3] four geometric isomers are possible.
How many isomers are possible for CO NH3 4Cl2 CL draw their structures?
Like [Co(NH3)4Cl2 ]+ (Figure 24.1), it has four ligands of one type and two of another. Consequently, it possesses two isomers: one with the Cl– ligands across the metal from each other (trans-Fe(CO)4Cl2) and one with the Cl– ligands adjacent (cis-Fe(CO)4Cl2).
Which type of isomerism is shown by CO NH3 4br2 CL?
Co(NH3)4Br2Cl will show both geometrical and ioinization isomerism.
What is the oxidation number of NH3?
Here the oxidation number of Nitrogen is -3 and that of Hydrogen is +1. Now, NH3 = 1(-3) + 3(+1) = -3 + 3 = 0. Hence it is a neutral molecule.
What is the coordination number of Cu NH3 4 2+?
The coordination number of copper in [Cu(NH3)4]2+ is 4. The Coordination number of an atom in a given molecule or a crystal refers to the total number of atoms, ion, or molecules bonded to the atom in question. The atoms, ions, or molecules that are bonded to the central atom (or molecule/ion) are called ligands.
Which type of ligand is NH3?
Ammonia (NH3) is known to be a strong field ligand since the donor atom in this case is nitrogen.
How do you find the coordination number of NaCl?
In NaCl crystal, each sodium ion is surrounded by 6 chloride ions and each chloride ion is surrounded by 6 sodium ions. So, the coordination number of NaCl as per definition will be 6:6.
How do you find the oxidation number and coordination number?
To determine the oxidation state of the metal, we set the overall charge equal to the sum of the ligands and the metal: +1 = −2 + x, so the oxidation state (x) is equal to 3+.
What are the coordination number in each cell?

What is coordination number cocl2 en 2?
The co-ordination number is 6.
What is the coordination number of cobalt in cocl2 en2?
152. In the complex [Co(en)2Cl2 ] Br, the co-ordination number and oxidation state of cobalt are. 6 and +1.
What is the coordination number of cobalt in Co en 3 3+?
In the complex ion, [Co(en3)3+] , the coordination number (CN) of Co is 6 because en (ethane -1,2-diamine) is a bidenate ligand and hence provides two donor atoms.
How many isomers are there for octahedral complex CoCl2 en )( NH3 2?
Two geometrical isomers i.e., cis and trans, cis isomer has two optical isomers i.e., d-cis isomer and l-cis-isomer.
What type of isomerism is shown by the complex CO NH3 5no2 Cl2?
Answer: It also show ionisation isomerism.
What type of isomerism is shown by the complex co en 2cl2 2+?
In [CoCl2(en)2],[CoCl2(en)2], coordination number of Co is 6 with octahedral geometry. Thus, [CoCl2(en)2] show geometrical isomerism.
What is geometrical isomers of CO NH3 4Cl2?
Geometric isomerism of [Co (NH3)4Cl2]+
The complex compound having two ligands occupying the adjacent position to each other is called cis-isomer while that in which the two ligands occupying the opposite position to each other is called trans-isomer.
Does CO NH3 4Cl2 have optical isomers?
The cis isomer of this octahedral complex ion has two planes of symmetry and the trans isomer has five such planes. So, it does not exhibit optical isomerism.
How many isomers can the complex cocl2 NH3 4 Cl form?
Synthesis of specific isomers of [CoCl2(NH3)4]Cl
The formation of the two isomers shown above, show how changes in reaction conditions can result in the production of different isomers. Reaction of [Co(CO3)(NH3)4]+ with concentrated HCl produces the cis isomer.
