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.

Expert Answer:

When P reacts with Q.
      C subscript 2 H subscript 5 O H rightwards arrow with C o n c. space H subscript 2 S O subscript 4 on top C H subscript 2 equals C H subscript 2 space plus space H subscript 2 O
P space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space Q

C H subscript 2 equals C H subscript 2 space plus space H subscript 2 rightwards arrow C subscript 2 H subscript 6

C subscript 2 H subscript 6 space plus O subscript 2 rightwards arrow 2 C O subscript 2 plus 3 H subscript 2 O
