Chemistry - Carboxylic acid and their Derivatives Question with Solution | TestHub

100 g of an impure sample of 3−methylbutan−2−one when treated with I₂/NaOH gives a compound X (yellow ppt) and a salt of carboxylic acid. The salt of carboxylic acid is converted into acid and treated with PCl₅ to give acetyl halide. When acetyl halide is mixed with anhydrous AlCl₃ and benzene gives 100 g of isopropylphenylketone. Find the % of 3− methylbutan−2−one in the sample.
