Question

Question One (Designed to make you think about symmetry & sub-groups of Ob) Cubane, C8H8, belongs to point group Oh. It is subjected to controlled fluorination (in which F atoms replace H atoms) yielding all possible species C8H8.F. Determine the point groups to which these species belong. Question Two (Designed to familiarize you with molecular vibrations) Consider the anionic species Ni(CN)s . Two forms are possible - trigonal bipyramidal (D3h ) and square pyramidal (C4 v ). Show, by use of group theory, that one may distinguish between these on the basis of their IR/Raman spectra for their C-N stretches. [HINT - The 5 C-N bonds transform exactly the same as the five Ni-C bonds.]
