Answer» `(C_(2)H_(5))_(3)COH` `(CH_(3))_(2)C(OH)CH_(3)` `(CH_(3))_(2)C(OH)CH_(2)CH_(3)` `(CH_(3))_(2)CHCH_(2)OH` Solution :`3^(@)`-alcohol cannot be oxidised by ALK. `KMnO_(4)`. During oxidation alk. `KMnO_(4)` forms a brown ppt. of `MnO_(2)`. Here, ALCOHOLS (A), (B) and (C) are `3^(@)` alcohols and as such can't be oxidised by alk. `KMnO_(4)`.
