1. a pungent smelling liquid (p)smelling like wine is heated with concentrated sulpfuric acid
    C2H5OH  + H2SO4  ?  C2H4  + HOH
        p                          q
 
and another compound (q)is formed.
2.    q    when treated with an acid r forms S.R is naturally produced in the stomach of animals.
    C2H4   +   HCl   ? C2H5Cl .
       q        r            s
 
3.Compound S when treated with aqueous Potassium hydroxide forms p again.
    C2H5Cl  + KOH  ? C2H5OH + KCl
 
p = C2H5OH .
q= C2H4.
r=    HCl  
s = C2H5Cl
