Question

Food cans are coated with Tin instead of Zinc, because

  1. Zinc is expensive than Tin.
  2. The melting point of Zinc is higher than Tin .
  3. Zinc is more reactive than Tin.
  4. Zinc is less reactive than Tin.

Answer:

Option C: Zinc is more reactive than Tin.

Detailed Solution:

The correct answer is “Zinc is more reactive than Tin.”.

Zinc is more reactive than Tin, and it can react with the acids present in food, leading to contamination. Tin, being less reactive, forms a protective layer and does not react with food easily.
