The color in KMnO4 arises from an electronic transition, but it is actually not a d-d ... When the light is reflected (or transmitted) it is missing the frequencies of the light absorbed, and so it looks pink.
Metal carbonyls of transition elements constitute another important class of organometallic compounds. All d-block elements which contain only carbonyl ligands are called homolepti
The electronic configuration of a metal M is 1s 2 , 2s 2 , 2p 6 , 3s 1 , The formula of its oxides will be: (1) MO (2) M
history of this reaction.is any ligand is needed for the reaction?
amphoterism of methanol Compound A is much more basic than compound B (charge effect). By the element effect, C is much more basic than A; this follows from the fact that if we
