On comparing chemical reactivity of `C^12 and C^14` , it is revealed that:

Options

A. `C^12` is more reactive
B. `C^14` is more reactive
C. Both are inactive
D. Both are equally active

Answer

To compare the chemical reactivity of carbon-12 (C-12) and carbon-14 (C-14), we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Composition of C-12 and C-14**:
- Carbon-12 (C-12) has 6 protons and 6 neutrons.
- Carbon-14 (C-14) has 6 protons and 8 neutrons.

2. **Determine the Number of Electrons**:
- Both isotopes have the same number of electrons, which is 6. This is because the number of electrons equals the number of protons in a neutral atom.

3. **Calculate the Neutron-to-Proton Ratio**:
- For C-12:
- Neutrons (N) = 6, Protons (P) = 6
- Neutron-to-Proton Ratio (N/P) = 6/6 = 1
- For C-14:
- Neutrons (N) = 8, Protons (P) = 6
- Neutron-to-Proton Ratio (N/P) = 8/6 = 4/3 (approximately 1.33)

4. **Analyze Stability Based on Neutron-to-Proton Ratio**:
- A neutron-to-proton ratio of 1 indicates stability (as seen in C-12).
- A neutron-to-proton ratio greater than 1 (as in C-14) indicates instability.

5. **Conclusion on Reactivity**:
- Since C-14 is unstable due to its higher neutron-to-proton ratio, it is more reactive than C-12, which is stable.

### Final Answer:
C-14 is more reactive than C-12.
