give reason-oxidation of ethanol with CrO3 produces ethanal, while ethanol when oxidised with alkaline KMNO4 produces ethanoic acid
Asked by ashutoshajt | 28 Jan, 2019, 11:30: PM
answered-by-expert Expert Answer
When ethanol reacts with chromic anhydride(CrO3), only partial oxidation occurs and ethanal is formed.

On the other hand, when ethanol is heated with alkaline potassium permanganate (KMnO4), it produces ethanoic acid due to complete oxidation.

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.
