In Ma2b2c2 type pls draw all geometrical, optical and stereoisomers. Actually I'm confused that if we change the order of a, b c in the compound then a new geometry is formed and that will also behave different to plane polarized light. So for this case we can arrange in 5 different orders of a2b2c2. So are all 5 optical isomers? And then if we take their mirror images then we'll Have 10 optical isomers as all 10 have diff rotation. So what is geometrical isomerism here?

Subject: Chemistry, asked on on 21/11/16

If [Cr(H2O)6]^3+ then here what will be the hybridization? It will be octahedral . But there are 3 electrons in d orbital of Cr3+ so it means two would pair and 1 would be alone so we'll be left with 3 empty orbitals of d? But for octahedral we have either d2sp3 or sp3d2 so as it is strong ligand so it should be d2sp3 which means 2 orbitals of d will hybridize but there are 3 empty orbitals. So 1 orbital of d will be empty and won't take part in hybridization?
