FAQs on Electrophilic Substitution in Halo Arenes Video Lecture - Chemistry for JEE Main & Advanced

1. What is electrophilic substitution in haloarenes?
Ans. Electrophilic substitution in haloarenes is a type of organic reaction where an electrophile replaces a hydrogen atom on an aromatic ring containing halogen atoms.
2. How does electrophilic substitution occur in haloarenes?
Ans. Electrophilic substitution in haloarenes occurs when an electrophile attacks the electron-rich aromatic ring, leading to the formation of a new substituted product.
3. What are some common electrophiles involved in electrophilic substitution in haloarenes?
Ans. Some common electrophiles involved in electrophilic substitution in haloarenes include nitronium ion (NO2+), sulfur trioxide (SO3), and halogens like chlorine and bromine.
4. What is the role of halogens in electrophilic substitution in haloarenes?
Ans. Halogens in haloarenes serve as activating groups that increase the electron density on the aromatic ring, making it more susceptible to electrophilic attack.
5. How does the presence of halogens affect the reactivity of haloarenes in electrophilic substitution reactions?
Ans. The presence of halogens in haloarenes increases the reactivity of the aromatic ring towards electrophilic substitution reactions due to their electron-donating nature, which helps stabilize the intermediate carbocation.
