The carboxylic acid can be distinguished from alcohol by performing the following tests:

 i.   Test with NaHCO3 solution in water:
     On adding carboxylic acid to baking soda, carbon dioxide is liberated with brisk effervescence.
     On adding a solution of baking soda to alcohol, no brisk effervescence occurs.
 
 ii.   Test with blue litmus solution: Carboxylic acid turns blue litmus red.
      There is no change in colour when a blue litmus solution is added to alcohol

CBSE 10 - Chemistry
A compound 'C' with molecular formula C2H4O2 reacts with Na metal to form compound 'R' and evolve a gas which burns with pop sound. 'C' reacts with an alcohol 'A' in presence of an acid to form a compound C2H4O2.  On addition of NaOH to 'C' it gives 'R' and water. 'S' on treatment with NaOH gives back 'R' and 'A'. Identify C,R,A,S and write down the reactions involved.

A carbon compound ‘P’ on heating with excess conc.  H2 SO4  forms another carbon compound ‘Q’ which on  addition of hydrogen in the presence of nickel catalyst  forms a saturated carbon compound ‘R’. One molecule  of ‘R’ on combustion forms two molecules of carbon  dioxide and three molecules of water. Identify P, Q  and R and write chemical equations for the reactions  involved.
