The starting material for the oxidation reaction shown below is:
Open in App
Solution
The correct option is B
Alkenes on reacting with acidified KMnO4 will get oxidised to ketone or acids.
Depending on the nature of the alkenes, the products formed after oxidation with acidic KMnO4 can be ketones and/or acids.
The double bonded carbon which doesnot have a hydrogen attached to it will get oxidised to form ketone.
In the product we have two ketone group, thus the starting material should have a two doubly bonded carbon atom without hydrogen attached to it.
Thus, compound (b) and (c) has two doubly bonded carbon atom without hydrogen attached to it.
The position of CH3CO is at 3rd position to the keto group.
Hence, compound (b) on oxidation will give the desired product.
