The reagent used in Hofmann elimination reaction is
Moist Ag2O
LiAlH4
Na-Hg/H2O
HNO2
The Correct Option is A
Solution and Explanation
Detailed Explanation:
What is Hofmann Elimination Reaction?
The Hofmann elimination reaction is a chemical reaction in which a quaternary ammonium hydroxide undergoes thermal decomposition to form an alkene. It is a type of β-elimination reaction.
Reaction Overview:
When a quaternary ammonium salt is treated with moist silver oxide (Ag2O), it converts into the corresponding quaternary ammonium hydroxide. Upon heating, this hydroxide undergoes elimination to yield an alkene, a tertiary amine, and water.
Reagent Used:
Moist Ag2O (silver oxide + water) is the correct reagent. It replaces the halide ion (like Br⁻ or I⁻) in the quaternary ammonium salt with an OH⁻ group to form the ammonium hydroxide.
Correct Answer: Moist Ag2O
