Document Summary

Key concepts in organic chemistry: alcohols, ethers & thiols (usselman version) The o atom is always ignored in calculations of units of unsaturation. The o in alcohols is sp3 hybridized (two sp3 orbitals are occupied by non-bonding pairs). The s atom is always ignored in calculations of units of unsaturation. In alcohol/thiol naming, the oh/sh group always takes priority over bonds. Alcohols are classed as 1 , 2 or 3 depending on the type of sp3 c atom to which the oh group is bonded. Hydrogen bond refers to the attractive force between an h + of one functional group and the - of the lone pair on the o (or other) atom of another. A hydrogen bond is not a true ( ) bond, but is instead a coulombic attraction between partial charges on atoms in neighbouring molecules. Alcohols tend to have very high boiling points for their size.
