Compound `(A)(C_(12)H_(16))` on oxidation with acideic `KMnO_(4)` solution gives acetone and . Identify compound `(A)`.

Text Solution

Verified by Experts

First, calculate the degree of unsaturation.
`D.U.=((2n_(C)+2)-n_(H))/(2)=((2xx12+2)-16)/(2)=5^(@)`

It means that ` 2 mol` of each of the products are obtained so that the total `C` atoms in the compounds `(A)` and in the products should be equal.

Two `(C=O)` groups of the acetones are joined with two `(C=O)` groups of the second compound and two `(COOH)` groups of the second compound are joined with two `(COOH)` groups of the same compound .
