. A carbon compound 'P' on heating with excess cone
H2S04 forms another carbon compound 'Q' which on addition of hydrogen in the presence of nickel catalyst forms 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.
Explanation: . . . .
• When ethanol is heated with excess of cone, H2S041 .it gets dehydrated-to form ethane (an unsaturated hydrocarbon)
• When ethene is heated with hydrogen. in the presence of nickel catalyst it form ethane (a saturated hydrocarbon)
