Question

Match the following:

List-I (Compound)	List-II (Use)
A) Kieselguhr	IV) To convert alcohol directly into gasoline
B) Silica gel	I) Chromatographic material
C) ZSM-5	III) Filtration plants
D) Hydrated zeolites	II) Softening of hard water

• A. A-IV, B-III, C-II, D-I
• B. A-IV, B-I, C-II, D-III
• C. A-III, B-IV, C-I, D-II
• D. A-III, B-I, C-IV, D-II

Hint:

Zeolites like ZSM-5 have specific catalytic applications; silica gel is commonly used in chromatography and desiccation.

Answer 1

The Correct Option is D

A) Kieselguhr is a porous material used in filtration → III
B) Silica gel is commonly used as a desiccant and in chromatography → I
C) ZSM-5 is a zeolite catalyst used in petrochemical cracking → IV
D) Hydrated zeolites are used to soften hard water by ion exchange → II
