Match the following : ( array llll & List I & & List II (A) & Teflon & I. & SnCl ₂ (B) & Anionic polymerisation & II. & C ₂ ~F ₁ (C) & Cationic polymerisation & III. & Bakelite (D) & Thermosetting polymer & IV. & Polystyrene & & V. & RLi array ) The correct answer is

Options

  1. A( array ccccc A & B & C & D II & I & V & III array )
  2. B( array ccccc A & B & C & D II & V & I & IV array )
  3. C( array ccccc A & B & C & D II & V & I & III array )
  4. D( array ccccc A & B & C & D V & II & I & IV array )

Correct answer

C. ( array ccccc A & B & C & D II & V & I & III array )

Step-by-step solution

(A) Monomer of teflon is ( C ₂ ~F ₄ ) (II). (B) (R Li ( V ) ) used in initiation of anionic polymerisation. (C) ( SnCl ₂ ) (I) used for cationic polymerisation. (D) Bakelite (III) is thermosetting polymer. Hence, option (3) is correct.
