Question

Match the conversion from List-1 with the process involved from List-2.

List - 1	List - 2
Conversion	Process involved
A)Benzene $\to$Cyclohexane	1) Controlled hydrogenation
B)Ethylene $\to$ Formaldehyde	2) Hydrogenation
C) Acetylene $\to$ Ethylene	3) Ozonolysis
D) Benzene $\to$ Toluene	4) Alkylation

• A. A-3, B-4, C-1, D-2
• B. A-1, B-2, C-3, D-4
• C. A-2, B-3, C-1, D-4
• D. A-4, B-3, C-2, D-1

Answer 1

The correct option is C A-2, B-3, C-1, D-4

Benzene to cyclohexane is a reaction of benzene with hydrogen in presence of Ni catalyst, so its a hydrogenation process. Benzene to toluene is friedal craft alkylation. Alkyne to alkene is done with lindlars catalyst, its is controlled reduction of alkyne. Alkene to aldehyde is ozonolysis process.
