Q. What is Electronic Isomerism?
Electronic Isomerism: The complex {Co (NH3)sNO]Cl2 exists in two forms. One is black paramagnetic while the other is pink and diamagnetic. Thorough structural studies show that the black isomer is a Co(ll) complex containing neutral NO group whereas the pink one is a Co(111) complex where NO- ion is present. This kind of isomerism is known as electronic isomerism.
The correct electronic configuration of Ti(Z= 22) atom is: (1) 1s 2 , 2s 2 , 2p 6 , 3p 6 , 4s 2 , 3d 2 , (2) 1s 2, 2s 2 , 2p 6 , 3p 6 , , 3d 4 , (3) 1s 2 , 2s
