QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Aromatic Organic Compounds and Reactions.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 11
Describe the difference between ortho, meta, and para positions in a disubstituted benzene ring.
Describe the effect of an electron-withdrawing group on the reactivity of benzene towards electrophilic substitution.
Describe the structure of benzene according to the resonance model.
Explain why benzene does not undergo addition reactions easily.
Explain why nitrobenzene is less reactive towards electrophilic substitution than benzene.
Explain why pyrrole is aromatic.
Name the reaction: Benzene + CH₃Cl/AlCl₃ → Toluene.
State Hückel's rule for aromaticity.
A student attempts to nitrate toluene and observes that the major products are ortho- and para-nitrotoluene. Explain why the methyl group directs the incoming nitro group to these positions.
Arrange the following compounds in increasing order of reactivity towards electrophilic aromatic substitution: benzene, chlorobenzene, phenol.
Calculate the number of π electrons in anthracene and state whether it is aromatic according to Hückel’s rule.
Explain why benzene is less reactive towards nucleophilic substitution reactions compared to electrophilic substitution reactions.
State the role of Lewis acids such as AlCl3 in the Friedel–Crafts alkylation of benzene.
