A compound ' A ' on reaction with ' X ' and ' Y produces the same major product but different by product ' a ' and ' b '. Oxidation of ' a ' gives a substance produced by ants. ' X ' and ' Y ' respectively are
Options
- AKMnO 4 / H + and dil. KMnO 4 , 273   K
- BKMnO 4 ,(dilute), 273   K and KMnO 4 / H +
- CKMnO 4 / H + and O 3 , H 2 O / Zn
- DO 3 , H 2 O / Zn and KMnO 4 / H +
Correct answer
D. O 3 , H 2 O / Zn and KMnO 4 / H +
Step-by-step solution
The substance produce by ants is formic acid, which is the product of oxidation of "a", means 'a' should be formaldehyde. Now, formaldehyde and ketons are prepared by reductive ozonolysis of alkenes. And by oxidation in presence of strong oxidising agents alkenes give ketons and acids.
