what happens when 5% alkaline potassium permanganate solution is added drop by drop to warm propyl alcohol propanol taken in the test tube explain with the help of chemical equation
Answers
When 5% alkaline potassium permanganate solution is added drop by drop to propanol taken in the test tube, then its purple colour disappears as it oxidizes the propanol to its respective carboxylic acid i.e. propanoic acid.
It is because alkaline potassium permanganate is known to be a strong oxidizing agent , which oxidizes the primary alcohol- propanol to propanal and then finally to propanoic acid.
Chemical equation:
alk. KMnO4
CH3CH3CH2OH ----->CH3CH3CH2COOH
Ethanol oxidized within the sight of KMNO4 to give ethanoic corrosive as the last item.
Ethanol gets oxidized to ethanoic corrosive because of the nearness of a ground-breaking oxidant specialist potassium permanganate.
At the point when KMNO4 added to the arrangement, the shade of the arrangement vanishes gradually.
The shade of the arrangement continues as before just on account of overabundance KMNO4.
