Match the catalysts to the correct processes. (A) TiCl3 (i) Wacker process

Question

Match the catalysts to the correct processes.

	Catalyst		Process
(A)	TiCl3	(i)	Wacker process
(B)	PdCl2	(ii)	Ziegler- Natta polymerisation
(C)	CuCl2	(iii)	Contact process
(D)	V2O5	(iv)	Deacon's process

 

Answer 1

Correct option (b)

Explanation:

(a) TiCl₃ is used as Ziegler-Natia catalyst for the polymerisation of ethene.

(b) PdCl₂ is used in Wacker process, in which alkene changed into aldehyde via catalytic the cyclic process initiated by PdCl₂.

(c) CuCl₂ is used in Deacon's process. (for.Cl₂)

(C) V₂O₅ is used in the contact process of manufacturing sulphuric acid.

Time-Saving Technique This type of questions can also be solved through elimination technique. There is no need to know all the four matches to select the correct response. Even if you know (b) matches then also you can solve the problem. e.g. suppose you know the usage of V₂O₅ in the contact process (i.e. D matches with (iii) and TiCl₃ is connected to Ziegler-Natta catalyst (i.e. A matches with ii).

These two combinations are present only in option number (b). Likewise, tor this question particularly if you know that V₂O₅ is used in contact process then this combination is present in option (b) only out of all the four option given. ln this way you can eliminate wrong options to get the correct response.
