a. Isomers (A) and (B), `C_(10)H_(12)O`, are isolated form the oil of bay leaf. They are insoluble in aq. NaOH and decolourise `Br_(2)//CCI_(4)` and `KMnO_(4)`. Each is vigorously oxidised to p-anisic acid, `(p-MeOC_(6)H_(4)COOH)`. Ozonolysis (A) and (B). Identify A and B

Explanation

To solve the problem, we need to identify the isomers A and B, which have the molecular formula C₁₀H₁₂O, and are derived from the oil of bay leaf. The key points provided in the question are:

1. Both isomers are insoluble in aqueous NaOH.
2. They decolorize bromine water and KMnO₄, indicating the presence of unsaturation (double bonds).
3. Upon vigorous oxidation, both isomers yield p-anisic acid (p-MeOC₆H₄COOH).
4. Ozonolysis of both isomers is mentioned.
