16. Which of the following is correct statement?
(1) [Ti(H20)]3+ is coloured complex
(2) [Si(H20)6]4+ is colourless complex
(3) d-d transition is not possible in [Si(H20)6]4+
complex
(4) All of these

what is d-d transition?
please answer only if u know the solution​

Answer 1

Explanation:

hope thishelpes

Answer 2

In a d-d transition, an electron in d orbital on the matal is exited by a photon to another d orbital of higher energy. in complexes of the transition metals, the d orbitals do not all have the same energy. in centrosymmetric complexes, d-d transitions are forbidden by the Laporte rule.
