Name  the  oxidising  agent   used   for   the   conversion  of  ethanol  to  ethanoic  acid. Distinguish  between ethanol and  ethanoic acid  on  the  basis  of  (i)  litmus test,  (ii) reaction with  sodium carbonate

Best Answer

Acidified K2Cr207 can be used as oxidising agent for the conversion of ethanol to ethanoic acid

Name  the  oxidising  agent   used   for   the   conversion  of  ethano

(i)  Litmus  test

 

• If an organic compound (to be tested)  does not change the colour of either of the litmus  solution  (blue  or  red)  then  the  organic  compound is neutral  in  nature. Ethanol is a neutral compound

 

• When some blue litmus solution is added to the organic compound (to be tested), if the blue litmus solution turns red; it shows that the organic compound is acidic and hence it is ethanoic acid

 

(ii)  Reaction with sodium carbonate

 

• When the organic compound (to be tested) is taken in a test tube and a pinch of sodium  carbonate  is added  to it if no reaction occurs in the reaction mixture, it is ethanol

 

• When the organic compound (to be tested)  is taken in a test tube and a pinch of sodium   carbonate   is  added   to  it;  evolution   of  carbon   dioxide   with   brisk effervescence shows  that the given organic compound is ethanoic acid
