Question

a carbon compound p on heating with excess conc.H2so4 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 do oxide and three molecules of water identify P,Q,R and write equation for the reaction invlved

Answer 1

P is ethanol

Q is ethene

R is Ethane

C2H5OH ---∆---->C2H2 +H2O

C2H2 + H2------Ni-------> C2H6

C2H6------combustion------2 co2+ H2o + H &L energy
