- How do substituent groups (G) on an aromatic ring influence the course of electrophilic aromatic substitution?
- How do the activating and deactivating effects account for the orientation of entering E+referred?
- Explain that halogens are o-, p- directors, but are deactivating.
- Compare the rate of nitration under similar conditions of Ph-O-Me and Ph-S-Me. Explain
- Why is PhNO2 a suitable solvent for the Friedel-Crafts alkylation of PhBr while benzene is not?
- Account for the greater reactivity and the o, p-orientation in electrophilic substitution of biphenyl despite the electron-attracting inductive effect of the phenyl group.
- How can a t-butyl substituent be used as a blocking group in aromatic electrophilic substitutions?
- Describe and account for the reaction , if any, of D2SO4 in D2O with (a) C6H5SO3H (b) C6H5OH (c) C6H6
- Why is Friedel-Crafts acylation but not alkylation of naphthalene practical?
- Give the product of acylation of naphthalene with CH3COCl and AlCl3 in the solvent (i) CS2 and (ii) PhNO2.
