Dear Farah,


The valence bond theory was fairly successful in explaining qualitatively the geometry and magnetic behaviour of the complexes. But, it could not explain the following :

(i) The origin of their absorption spectra could not be explained.

(ii) Why did different complexes of the same metal show different colours.

(iii) Relative stabilities of different complexes could not be explained.

(iv) Why should certain ligands form high spin, while others low spin complexes.

Best Of Luck...!!!!

What favours the hydride shift in Cannizaros Reaction? We know the hydride is a very poor leaving gropu so why does it leave then?
since we know that hydride shift is RDS in Cannizaro reaction and the carbon cannot exceed its covanlency to 5 also the double bond btw C and O is stronger then hydride it will leave for a...

the group that leaves is basically that group group which doesnt has any role in giving stability
priyanshu gautam 11 months ago
but instead of hydride going out , OH- can leave since it is a much better leaving group than H-
