Compound A(C9H10O)A\left({C}_{9}{H}_{10}O\right) shows positive iodoform test. Oxidation of A with KMnO4/KOHKMn{O}_{4} / KOH gives acid B(C8H6O4)B\left({C}_{8}{H}_{6}{O}_{4}\right) . Anhydride of B is used for the preparation of phenolphthalein. Compound A is:Compound A( C _ 9 H _ 10 O) shows positive iodoform test. Oxidation of A with KMn O _ 4 / KOH gives acid B( C _ 8 H _ 6Compound A( C _ 9 H _ 10 O) shows positive iodoform test. Oxidation of A with KMn O _ 4 / KOH gives acid B( C _ 8 H _ 6Compound A( C _ 9 H _ 10 O) shows positive iodoform test. Oxidation of A with KMn O _ 4 / KOH gives acid B( C _ 8 H _ 6Compound A( C _ 9 H _ 10 O) shows positive iodoform test.
