Which of the following compounds will undergo nucleophilic aromatic substitution with methoxide ion at the fastest rate?
B)1 1ec7e89_7ac1_e6f8_9927_f7309a5170d9_TB34225555_11

Question

Quizplus · Accepted Answer

The compound in option B has a good leaving group (bromine) and a strong electron withdrawing group (NO2) on the benzene ring. This combination makes the carbon atom attached to the bromine very electrophilic, which makes it susceptible to nucleophilic attack by the methoxide ion. Therefore, compound B will undergo nucleophilic aromatic substitution at the fastest rate.
