Question

1. Write the d-orbital configuration of [Ti(H₂O₆]²⁺

2. Ti⁴⁺ is colourless. Why?

3. Write the possible isomers of [Co(NH₃)₅Br] SO₄ and name them.

Answer 1

1.

2. In Ti⁴⁺ there are no electrons in 3d orbitals. Hence ‘d-d’ transition cannot take place. Hence it is colourless.

3. Possible isomers of [Co(NH₃)₅ Br] SO₄ and names

[CO(NH₃)₅Br] SO – Pentamminebromido- cobalt(III) sulphate

[Co(NH₃)₅SO₄]Br - Pentamminesulphatecobalt(III) bromide
