A carbon compound „P‟ on heating with excess conc. H2SO4forms 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.[5]

Answer:
Explanation:
The compound 'P' is Ethanol. When it is heated with concentrated sulphuric acid, it gets dehydrated and forms Ethene. So, the compound 'Q' is Ethene.
(Q) When Hydrogen is added to Ethane, in presence of Ni catalyst. it forms an unsaturated hydrocarbon i.e. Ethane. So, the compound 'R' is Ethane.
(R) On combustion reaction of ethane, the products formed are:

Answer:
Explanation:
ch3ch2oh = ch2ch2 + h2o
P is ch3ch2oh (ethanol)
Q is ch2ch2 (ethene)
ch2ch2 = ch3 ch3
R is ch3ch3
