Question

1-Butyne reacts with cold alkaline KMnO4 to produce

Answer 1

CH3C(triple bond)CCH3 + KMnO4 --- --------> (above the arrow H2O) , CH3C(double bond) O (single bond) C (double bond) O ( single bond CH3)

Please mark as me as brainly

Answer 2

Answer:

Explanation: CH3-CH2-CH=_CH + Cold alkaline kmno4-----------> CH3CH2COOH + HCOOH

But, a point is note here, in hot alkaline kmno4 the formic acid (HCOOH) is bring and CO2 +H2O is formed.

CH3CH2CH=_CH +hot alkaline kmno4----------> CH3CH2COOH + CO2 + H2O
