During the electrophilic substitution reaction of haloarenes, para substituted derivative is the major product.

Question 2:During the electrophilic substitution reaction of haloarenes, para substituted derivative is the major product.

The correct answer is – Yes, that’s correct. In an electrophilic substitution reaction of haloarenes, the para-substituted derivative is generally the major product. This is due to the influence of the ortho- and para- directing groups on the reaction mechanism. In electrophilic substitution reactions of haloarenes, the halo group acts as an electron-withdrawing group, deactivating the aromatic ring towards electrophilic attack. The presence of an ortho- or para- directing group can further increase or decrease the electron density at the reaction site, respectively. Due to this electronic effect, electrophilic attack is favored at the para-position, leading to the formation of the para-substituted derivative as the major product. This electronic effect is known as the para-director effect.
