WebThe basicity of alkoxide ions increases while going from primary to tertiary. This increase in basicity occurs because the conjugate base of a weak acid is strong. The weaker the acid, the stronger the conjugate base. Alkyl halide formation Alcohols are converted to alkyl halides by S N 1 and S N 2 reactions with halogen acids. WebBecause of the stability of tertiary carbocations, tertiary alcohols are the easiest to dehydrate and even 30% aqueous sulfuric acid can be used at temperatures below 100 °C.
