The three bidentate ligands can connect to the octahedral sites of the metal in a right handed or left handed fashion, similar to the blades on a propeller or the threads on a screw. The following five rules are used for naming complexes: When the complex is either a cation or a neutral molecule, the name of the central metal atom is spelled exactly like the name of the element and is followed by a Roman numeral in parentheses to indicate its … You recognise optical isomers because they have no plane of symmetry. Your IP: 173.255.200.141 The visual cortex of the brain is the area of the cerebral cortex that processes visual information.It is located in the occipital lobe.Sensory input originating from the eyes travels through the lateral geniculate nucleus in the thalamus and then reaches the visual cortex.

You can draw a mirror plane and see if the mirror image is superimposable on the original: *mol | lom* but there is a much easier way that involves Group theory: if the cmplx has a mirror plane σh (σv) then it cannot be chiral (and exhibit optical activity). At pH5.5 and 6.5 it has lower activity (one tenth more or less).
