Table 12. 2 Classification of Substituents in Electrophilic Aromatic Substitution Reactions 12.12 Substituent Effects in Electrophilic Aromatic Substitution:... compounds: electrophilic substitution reactions Answers to worked examples WE 22.1 Aromatic and anti-aromatic compounds (on Bromination of benzene leads to a single product because all the carbon atoms are identical. For mono-substituted benzenes, such as A, up to three products B, C and D are formed. Regioselective bromination will depend on which positions in this molecule are more

Aromatic electrophilic substitution (Ar-SE) Reactions The special reactivity of aromatic systems towards electrophiles arises mainly from two factors: the presence of π electron density above and below the plane of the ring - making it nucleophilic, and the drive to regain the aromatic character by opting for substitution as opposed to a simple addition reaction. Preference towards addition

- 64) In electrophilic aromatic substitution reactions, a phenyl substituent on the aromatic ring is: A) a deactivator and an o,p-director. B) an activator and an o,p-director. C) an activator and a m-director. D) a deactivator and a m-director. E) none of the above.
- - further electrophilic substitution of a disubstituted benzene is governed by the same resonance and inductive effects - must consider additive effects of the two groups on the ring
- Benzene reacts with electrophiles in substitution reactions. Another atom, or group of atoms, replaces a Another atom, or group of atoms, replaces a hydrogen atom on the benzene ring, and the product retains the stable aromatic ring.
