Which of the following is a catalytic process used in industry? MCQ with Answer and Explanation

Which of the following is a catalytic process used in industry?
A. Solvay process
B. Bayer's process
C. Hall-Héroult process
D. Haber process
Answer: Option D
Solution (By JKExamLibrary)
Haber process synthesizes ammonia using iron catalyst. Solvay process for soda ash uses no solid catalyst but involves reactions with CO₂ and ammonia. Bayer's process for alumina uses NaOH, no catalyst. Hall-Héroult process is electrolytic for aluminium. Catalysis is key in many industrial processes: Contact (V₂O₅), Ostwald (Pt), hydrogenation (Ni).

Question #1
The functional group present in aldehydes is:
A. -COOH
B. -CO-
C. -OH
D. -CHO

Correct Answer: Option D


Explanation:
Aldehydes are organic compounds containing the formyl group, -CHO, where a carbon atom is double-bonded to an oxygen atom and single-bonded to a hydrogen atom. -OH is the hydroxyl group (alcohols), -COOH is the carboxyl group (carboxylic acids), and -CO- is the carbonyl group (ketones).

Question #2
During electroplating of silver on a copper spoon, the electrolyte used is:
A. Copper nitrate solution
B. Sodium chloride solution
C. Copper sulfate solution
D. Silver nitrate solution

Correct Answer: Option D


Explanation:
In electroplating, the electrolyte must contain the ions of the metal to be deposited. To plate silver, a solution of a silver salt, such as silver nitrate (AgNO₃) or silver cyanide, is used. The anode is pure silver, and the cathode is the copper spoon to be plated.

Question #3
Atoms of different elements having same mass number are called:
A. Isotones
B. Isobars
C. Isotopes
D. Isomers

Correct Answer: Option B


Explanation:
Isobars: same mass number, different atomic number. Example: ⁴⁰Ar, ⁴⁰Ca. Isotopes: same atomic number, different mass number. Isotones: same number of neutrons. Isomers: same molecular formula, different structure.
