Q. Isomerism in Coordination Compounds?
You have already learnt about isomerism in your earlier studies. The phenomenon of isomerism is not restricted to organic compounds only but is quite frequently observed with coordination compounds. Whenever we come across compounds with the same chemical composition but different arrangement of atoms we call them isomers. Isomerism in complexes can be broadly classified into (a) structural and (b) stereo-isomerism.
