a pungent smelling liquid (p)smelling like wine is heated with concentrated sulpfuric acid and another compound (q)is formed. q when treated with an acid r forms a compound S.R is naturally produced in the stomach of animals.Compound S when treated with aqueous Potassium hydroxide forms p again.Identify P,Q,R andS with balanced equation

1. a pungent smelling liquid (p)smelling like wine is heated with concentrated sulpfuric acid

    C₂H₅OH  + H₂SO_{4  ?}  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.

    C₂H_{4   +}   HCl   ? C₂H₅Cl .

       q        r            s

 

3.Compound S when treated with aqueous Potassium hydroxide forms p again.

    C₂H₅Cl  + KOH  ? C₂H₅OH + KCl

 

p = C₂H₅OH .

q= C₂H_4.

r=    HCl  

s = C₂H₅Cl
