Which of the following is correct order of the reactivity of the metals?

Options

A. `Zn gt Fe gt Al gt Cu`
B. `Al gt Fe gt Zn gt Cu`
C. `Zn gt Al gt Fe gt Cu`
D. `Al gt Zn gt Fe gt Cu`

Answer

To determine the correct order of reactivity of metals, we can refer to the reactivity series, which ranks metals based on their ability to displace other metals from solutions and their general reactivity with acids and water.

### Step-by-step Solution:

1. **Understand the Reactivity Series**: The reactivity series is a list of metals arranged in order of decreasing reactivity. The most reactive metals are at the top, while the least reactive are at the bottom.

2. **Identify Key Metals**: From the video transcript, we can identify the following metals and their relative reactivity:
- Potassium (K)
- Sodium (Na)
- Magnesium (Mg)
- Aluminum (Al)
- Zinc (Zn)
- Iron (Fe)
- Lead (Pb)
- Hydrogen (H)
- Copper (Cu)
- Silver (Ag)
- Gold (Au)

3. **Determine the Correct Order**: According to the reactivity series mentioned in the transcript, the order of reactivity for the metals in question is:
- Aluminum (Al)
- Zinc (Zn)
- Iron (Fe)
- Copper (Cu)

4. **Conclusion**: Therefore, the correct order of reactivity of the metals is Aluminum > Zinc > Iron > Copper.

### Final Answer:
The correct order of reactivity of the metals is Aluminum > Zinc > Iron > Copper.
