Question 1
1 / -0

The compound formed as a result of oxidation of ethyl benzene by KMnO₄ is:

A
benzoic acid

B
benzyl alcohol

C
benzophenone

D
acetophenone

Solution

Any aliphatic carbon with hydrogen attached to it, in combination with benzene ring, will be oxidized to benzoic acid by KMnO4/H⁺.
Question 2
1 / -0

Match the catalysts to the correct processes :
Catalyst Process
(A) TiCI₃ (i) Wacker process
(B) PdCI₂ (ii) Ziegler - Natta polymerization
(C) CuCI₂ (iii) Contact process
(D) V₂O₅ (iv) Deacon's process

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

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

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

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

Solution

TiCI₃ → Ziegler-Natta polymerisation
PdCI₂ → Wacker process
CuCI₂ → Deacon's process
V₂O₅ → Contact process
Hence, option B is correct
Question 3
1 / -0

In strong alkaline solution MnO₄^– changes to

A
MnO₄^2–

B
MnO₂

C
Mn₂O₃

D
MnO

Solution

In strongly alkaline medium:
MnO₄^–+ e^–↔ MnO₄^2–
