Document Summary
October 24, 2012: alcohols, ethers and thiols. O atom is always ignored in the calculations of units of unsaturation: oxygen is zero when doing calculations for unsaturation. O is sp3 hybridized: 2 sp3 orbitals occupied by lone pairs. Thiols are alcohols where sulfurs has replaced an oxygen. S is also always ignored in calculations of unit of unsaturation. When naming alcohols- oh take priority over the pi bonds. Alcohols are classified as primary secondary and tertiary depending on the sp3 carbon atom. The oxygen has lone pairs on it meaning it can function as a base. The hydrogen can function as an acid. Look at what circumstances it acts as an acid and what circumstances it acts as a base. Polarity is less in thiols because it is less electronegative than o: other then than everything else is the same as alcohols. Hydrogen bond is more like an ionic bond attraction of opposite electron charges.
