Document Summary
Things like electronic configuration how the d orbitals are arranged interms of x2, y2, z2, etc all (cid:374)eed the(cid:396)e to (cid:271)e (cid:374)o iso(cid:373)e(cid:396)s. i(cid:374) (cid:395)uestio(cid:374)s o(cid:374) the e(cid:454)a(cid:373), (cid:449)e (cid:449)o(cid:374)"t ha(cid:448)e the(cid:373). Octahedral two triangles on top of each other? this one has enatiomers. Bidentate ligands mess up the isomers the two donor atoms have to be adjacent. Geometric isomers for ma2b4: as are opposite, as make 90degree angle. Geometric isomers for ma2b2 in square planar: as are opposite, as make 90degree angle. All geometric isomers for ma3b3 complex: as form t-shape, as do(cid:374)"t fo(cid:396)(cid:373) t shape, facial all three on corners of triangle, medidinal all three in t-shape. All geometric isomers for mabcd complex in planar: a opposite b, a opposite c, a opposite d. Optical isomer = enantiomer = chiral = non-superimposable mirror images. In octahedral, put them in octahedral and put one on top.
