Chem 220 Notes Page 1 Ch. 01 and 02: Structure and Bonding of Organic Molecules I. Types of Chemical Bonds A. Why do atoms forms bonds?  Atoms want to have the same number of electrons as the nearest noble gas atom (noble gas configuration). This requires having a completely full or completely empty valence shell of electrons.  Most main groups atoms will try to have eight valence electrons to completely fill their valence shell; this is the octet rule. There are some exceptions: hydrogen…

imaging mass spectrometry Essay

Chapter 1 1. Introduction: 1.1 Ambient mass spectrometry Mass spectrometry is an essential analytical tool in chemistry, biochemistry, pharmacy, medicine and many other related sciences. It is used in structural elucidation of unknown compounds using m/z ratio of fragmented ions. . ‘Ambient mass spectrometry’ allows direct analysis of samples in their native state in an open air environment. This leads to generation of ions and neutrals outside the vacuum system allowing unique experiments to be…

Linkage Isomerism Of Some Cobalt Complexes

isomerism etc. (see CH160 lecture notes). Linkage isomers arise because some ligands can bond via one donor atom in one compound, but via a different atom of the same ligand in another compound. Typical examples of linkage isomersism are: NO2– M-NO2 nitrito-κN (formerly nitro) M-ONO nitrito-κO (formerly nitrito) CN– M-CN cyanido-κC (formerly cyano) M-NC cyanido-κN (formerly isocyano) NCS M-SCN thiocyanato-κS (thiocyanato) M-NCS thiocyanato-κN (isothiocyanato) (Note the old names are given for some…
