Common mistakes
Confusing benzene with alkenes
Students often describe benzene as having alternating single and double bonds like alkenes.
Fix itBenzene has delocalized electrons and does not have fixed single or double bonds; it is represented by resonance structures.
Confusing electrophilic substitution with electrophilic addition
Students often confuse the two mechanisms, thinking that benzene can undergo addition reactions like alkenes.
Fix itRemember that benzene's stability comes from its aromaticity, which is preserved in substitution reactions, not in addition.
Confusing electrophiles with nucleophiles
Students often confuse electrophiles (electron acceptors) with nucleophiles (electron donors).
Fix itRemember that electrophiles seek electrons to react, while nucleophiles donate electrons.
Confusing electrophiles in reactions
Students often confuse the electrophile in nitration with that in Friedel-Crafts reactions.
Fix itRemember that the electrophile in nitration is the nitronium ion (NO2+), while in Friedel-Crafts alkylation, it is the carbocation formed from the alkyl halide.
