S
Figure 5
Draw the chemical structures of regioisomeric compounds R and S.
(ii) Using possible resonance contributors of P and Q predict which of the two
regioisomers will be favoured in the reaction.
(iii) Using curly arrows, draw the mechanism for the reaction of P and Q to form the
dominant regioisomer you have predicted in your answer to part (ii) above.
