1.	Which of the following alcohol will give a black precipitate of manganese dioxide with alkaline KMnO_(4) ?
Answer» `CH_(3)CH_(2)OH` `CH_(3)-underset(CH_(3))underset(\|)(CH)-underset(CH_(3))underset(\|)overset(OH)overset(\|)(C)-CH_(3)` `(CH_(3))_(3)C-OH` All of the above Solution :Out of the given three choices (A, B and C) B and C are `3^(@)` alcohols ANS as such not oxidised with mild oxidising agents like alkaline `KMnO_(4)`. In the reaction `KMnO_(4)` is itself reduced to `MnO_(2)` (black ppt.)
