(B) PdCl2 (ii) Ziegler -Natta
(C) CuCl2 (iii) Contact process
(D) V2O5 (iv)Deacon's process
  • (A)- (iii), (B)-(ii), (C)-iv, (D)- (i)

  • (A) - (ii), (B) - (i), (C) -(iv), (D) - (iii)

  • (A)- (ii), (B)- (iii), (C)- (iv), (D) - (i)

Answer

B.

(A) - (ii), (B) - (i), (C) -(iv), (D) - (iii)

(i) TiCl3 is used as Ziegler- Natta catalyst for the polymerisation of ethene.
(ii) PdCl2 is used in Wacker process, in which alkene changed into aldehyde via catalytic cyclic process initiated by PdCl2.
(iii) CuCl2 is used in Deacon's process (for Cl2)
(iv) V2O5 is used in contact process manufacturing sulphuric acid.
