Document Summary

Chemistry 2213a fall 2012 western university. Alcohols, ethers, and thiols: structure and nomenclature: alcohols and thiols. Alcohols have the general formula r oh, while thiols, the oxygen counterpart of alcohols, have the general formula r sh. The o atom has a valence of 2, and one of these is taken by the h. thus, the. Oh group substitutes an h atom in general formulas. So, the o atom is always ignored in unsaturation calculations. In nomenclature, the oh or sh group is given the lowest possible number in the carbon chain. Ch3ch2ohc2h6oc6h6o0unitsunsat. 4unitsunsat. ohoh3-buten-2-ol in complex molecules, oh can be treated as a hydroxy substituent. Like alkyl halides, alcohols are classified as 1 , 2 , or 3 depending on the number of carbon atoms bonded to the carbon bearing the oh group: physical properties of alcohols and thiols. The properties of alcohols stem from the high electronegativity of oxygen, resulting in polar bonds.
