Chemical properties of ethanol
The video explains the chemical reaction of conc. sulphuric acid and sodium metal with ethanol.
- properties of ethanol ?

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.
- Why is unsaturated fatty acids are added in soap
- 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.
