QuestionReaction mechanism / kinetic isotope effect in SEAr
Which one of the following statements is correct regarding the reaction mechanism, if we assume the presence of kinetic isotope effect in aromatic electrophilic substitution ?
- (a) C₆D₆ will react faster than C₆H₆ under identical reaction conditions.
- (b) The formation of σ-complex is a rate determining step.
- (c) The o/p-ratio of the products formed from anisole will be less than that of 4-deuterioanisole.
- (d) The D/H ratio will be higher in the reactant than the major product formed when 1,3,5-trideuteriobenzene undergoes mono-electrophilic substitution reaction.
