FAQs on Hydrocarbons: Directing Groups Video Lecture - Chemistry Class 11 - NEET

1. What are directing groups in hydrocarbons?
Ans. Directing groups in hydrocarbons are functional groups or substituents that influence the regioselectivity of a reaction. They direct the incoming reagent to a specific position on the hydrocarbon molecule.
2. How do directing groups affect the regioselectivity of a reaction?
Ans. Directing groups affect the regioselectivity of a reaction by influencing the electron density distribution in the hydrocarbon molecule. They can either activate or deactivate specific positions, making them more or less reactive towards the incoming reagent.
3. Can you provide examples of common directing groups in hydrocarbons?
Ans. Some common directing groups in hydrocarbons include -OH (hydroxyl), -NH2 (amino), -COOH (carboxyl), -CHO (aldehyde), -C(O)R (ketone), -CN (cyano), and -NR2 (dialkylamino).
4. How do directing groups influence the regioselectivity in electrophilic aromatic substitution reactions?
Ans. In electrophilic aromatic substitution reactions, directing groups activate specific positions on the aromatic ring, making them more susceptible to electrophilic attack. They can either activate ortho and para positions (ortho-para directors) or meta positions (meta directors) based on their electron-donating or electron-withdrawing nature.
5. Are there any exceptions to the regioselectivity rules imposed by directing groups?
Ans. Yes, there are exceptions to the regioselectivity rules imposed by directing groups. Factors such as steric hindrance and neighboring groups can sometimes override the directing effect of a group and lead to unexpected regioselectivity in a reaction. Additionally, certain reactions may not follow the usual regioselectivity patterns due to specific reaction conditions or other factors.
