Separation schemes, sequential addition of water solutions of acid and base to the organic solution of the mixture. Salts form and go into the water; come out again as free acid or free base when neutralized, dissolve again in the organic solvent. Combustion analysis burns the organic cpn to water and CO 2 ; wts can be used to calc. %C and %H. Analyze for other elements (except O), get ratio of atoms = empirical formula. Molecular weight gives the molecular formula. [do not attempt to memorize historical facts or episodes--not important] Nomenclature: no direct questions based on nomenclature. It will help if you can easily translate a name into a structure; nothing complicated nor tricky. Correlate structure with hybridized orbitals . 3 hybridizations: sp 3 = tetrahedral (4 sigma bonds). sp
