Q 1 :    

The metal atom present in the complex MABXL (where A, B, X and L are unidentate ligands and M is metal) involves sp3 hybridization. The number of geometrical isomers exhibited by the complex is:                                         [2024]

  • 3

     

  • 0

     

  • 4

     

  • 2

     

(B)

Tetrahedral complexes do not show geometrical isomerism.

 



Q 2 :    

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R).

 

Assertion (A): The total number of geometrical isomers shown by [Co(en)2Cl2]+ complex ion is three.

 

Reason (R): [Co(en)2Cl2]+ complex ion has an octahedral geometry.

 

In the light of the above statements, choose the most appropriate answer from the options given below:                           [2024]

  • (A) is correct but (R) is not correct.

     

  • Both (A) and (R) are correct and (R) is the correct explanation of (A).

     

  • (A) is not correct but (R) is correct.

     

  • Both (A) and (R) are correct but (R) is not the correct explanation of (A).

     

(C)

      [Co(en)2Cl3]+ has two geometrical isomers, cis and trans, and having octahedral geometry as its C.N. = 6.
