*Multiple options can be correct
Test: Bonding in Metal Carbonyls and Applications of Coordination Compounds (January 3) - Question 6

Orie or More than One Options Correct Type

Direction (Q. Nos. 11-15) This section contains 5 multiple choice questions. Each question has four choices (a), (b), (c) and (d), out of which ONE or MORE THAN ONE are correct.

Q. 

Which of the following forms a metal carbonyl corresponding [M(CO)6]?

Detailed Solution for Test: Bonding in Metal Carbonyls and Applications of Coordination Compounds (January 3) - Question 6

Stable complex is obtained when sum of metal d-electrons and electrons donated by ligands and the overall charge of the complex equals to 18. Chromium and tungsten obey 18-electron rule or effective atomic number rule.
In [Cr(CO)6]
Atomic number of chromium = 24
∴ Cr contains electrons = 24 e- 
6 CO ligand donate (6 x 2 electrons) = 12 e-
EAN of [Cr(CO)6] = 36e- 
Thus, it may be stated that the complex [Cr(CO)6] obeys EAN rule and it will be stable complex. [W(CO)6] can be solved same as above.

*Multiple options can be correct
Test: Bonding in Metal Carbonyls and Applications of Coordination Compounds (January 3) - Question 7

Which is the correct?

Detailed Solution for Test: Bonding in Metal Carbonyls and Applications of Coordination Compounds (January 3) - Question 7

[Fe(NCS)6]3-, [Fe(H2O)6]2+ ,[Cu(H2O)4]2+ are correct.

Test: Bonding in Metal Carbonyls and Applications of Coordination Compounds (January 3) - Question 8

Detailed Solution for Test: Bonding in Metal Carbonyls and Applications of Coordination Compounds (January 3) - Question 9


Each cobalt atom is bonded to three terminal CO group and share two CO ligands as bridging groups.

Test: Bonding in Metal Carbonyls and Applications of Coordination Compounds (January 3) - Question 10

Statement Type

Direction (Q. No. 25) This section is based on Statement I and Statement II. Select the correct answer from the codes given below.

Q. 

Statement I : Mn(π— C3H5)(CO)4, obey effective atomic number rule.

Statement II : π-allyl ligand act as a 3e- donor.

Detailed Solution for Test: Bonding in Metal Carbonyls and Applications of Coordination Compounds (January 3) - Question 10

In Mn(π -C3H5) (CO)4
Mn= 25
π-C3H5 = 3
4 (CO) = 8
Hence, EAN = 36
Hence, π-C3H5 ligand acts as a 3-electron donor and complex obey effective atomic number rule.
