Solution


Q.

Given below are two statements:                                            [2025]

Statement (I): In octahedral complexes, when Δo < P high spin complexes are formed. When Δo > P low spin complexes are formed.

Statement (II): In tetrahedral complexes because of Δt < P, low spin complexes are rarely formed.

In the light of the above statements, choose the most appropriate answer from the options given below:
1 Statement I is correct but Statement II is incorrect  
2 Both Statement I and Statement II are incorrect  
3 Statement I is incorrect but Statement II is correct  
4 Both Statement I and Statement II are correct  

Ans.

(4)

Statement I:

Statement II:

Δt=49Δ0<P, so low spin complexes are rarely formed for tetrahedral complexes.
