On completion of this course, the students will be able to- CO83:classify and discuss the systematic nomenclature of organometallic compounds. CO84:calculate valence electron counts in organometallic compounds CO85:discuss the symmetry, structure and bonding of M-C s bonded and M-C multiple bonded organometallic compounds CO86:describe in detail the reaction mechanisms of various homogeneous and heterogenous catalysts. CO87:differentiate between terminal and bridging carbonyls and will be able to interpret the type of bonding on the basis of IR spectra. |
