Which of the following can be used as reagent in Friedel Crafts reaction?
Options:(select one or more)
Answer:
Solution:
Question Explanation:
The question asks to identify which of the four given options can act as a reagent (alkyl or acyl halide) in a Friedel-Crafts reaction.
Concept:
This question is based on Friedel-Crafts Reaction.
Solution:
A successful Friedel-Crafts reaction requires the alkyl or acyl halide to react with the Lewis acid to form a stable electrophile (carbocation or acylium ion).
Vinyl halides (CH2 =CH–Cl), aryl halides (Ar–Cl), and amides do not function as reagents in Friedel Crafts reactions. This is because these halides are unable to form the cations necessary for an electrophilic reaction. Nitrobenzene, being inert to Friedel-Crafts reactions, can be utilized as a solvent in this process. CH3CH2 Cl and CH2=CH–CH2–Cl are the source of electrophile for the Friedel Craft reaction.
Final Answer: Option (C and D)
