‘Some examples of positively charged electrophiles are the hydronium ion, nitronium ions, metal ions, and carbocations.’
‘All carbocations are strong alkylating agents with a high affinity for groups which donate or share their electrons, such as halide ions, hydroxyl anions and amines.’
‘The resulting esters generate carbocations that react with DNA.’
‘The methyl carbocation, CH 3 + is the least stable carbocation.’
‘Therefore, all such red-shifted pigments are believed to be highly delocalized, bond-equalized carbocations.’
