Concept introduction:
Benzene undergoes electrophile substitution. The kinetics of the electrophilic substitution reaction depends upon the nature of substituent present on the benzene ring. Electron releasing groups activates the ring towards the electrophilic substitution reaction while electron withdrawing groups deactivates the ring towards the electrophilic substitution reaction.
Answer to Problem 18.15P
The product formed by the reaction of given compound with
The reaction occurs slower because benzene ring contains deactivating group.
Explanation of Solution
Electron withdrawing groups deactivates the ring towards the electrophilic substitution reaction.
The substituent present in the given compound is electron withdrawing group. Thus, it directs the electrophile to meta position and deactivates the ring towards the electrophilic substitution reaction. Hence, the given compound reacts slower than benzene. The reaction is shown below.

- Hydration of aldehydes and ketones can be catalyzed by acid or base. Bases catalyze hydration by: protonating the carbonyl oxygen making the carbonyl group more electrophilic employing hydroxide ion, which is a better nucleophile than water making the carbonyl group less electrophilic shifting the equilibrium position of the reaction to favor productsarrow_forward1-Octen-3-ol is a potent mosquito attractant commonly used in mosquito traps.
