3. The reaction of P4 with X leads selectively to P4O6. The X is
(A) Dry O2 (B) A mixture of O2 and N2
(C) Moist O2 (D) O2 in the presence of aqueous NaOH
Sol. (B)
P4 + 3O2 2 N → P4O6 (exclusively)
(N2 is used to retard the further oxidation.)
4. Among cellulose, poly(vinyl chloride), nylon and natural rubber, the polymer in which the intermolecular
force of attraction is weakest is
(A) Nylon (B) Poly(vinyl chloride)
(C) Cellulose (D) Natural Rubber
Sol. (D)
As chain of natural rubber involves weak van der Waal force of interaction.
