Azinc is costlier than tin
Bzinc melts at a higher temperature
Czinc is less reactive than tin
Dzinc is more reactive than tin
Answer & Solution
Correct answer: D. zinc is more reactive than tin
1. A coating on food cans must be fairly unreactive so it does not contaminate the food.
2. **Zinc is more reactive than tin**, so a zinc coating would react with the food; tin is less reactive and safer.
3. Hence tin (not zinc) is used to coat food cans.
