5.A Alcohols






5.A.1 Description

5.A.1.a nomenclature

Alcohols are organic compounds containing a hydroxyl (i.e. -OH) group. Although the group may look similar to water (H2O), the CO bond is about 1.5x as long as the OH bond.

5.A.1.b physical properties

5.A.2 Important reactions

5.A.2.a substitution reactions (SN1 or SN2, depending on alcohol and derived alkyl halide)
