Options

A.
B.
C.
D. `underset(I)overset(Ө)(CH_(3)) gt overset(Ө)Cunderset(II)(D_(3))" "I gt II`

Answer

To determine the correct stability order of anions, we need to analyze the factors that influence the stability of anions, such as resonance, inductive effects, and the electronegativity of atoms involved.

### Step-by-Step Solution:

1. **Identify the Anions in Each Option**:
- Look at the anions mentioned in each option. For example, you might have anions like NO2^-, CN^-, Cl^-, etc.

2. **Consider Resonance Effects**:
- Anions that can delocalize their negative charge through resonance are generally more stable. For example, the nitro group (NO2) can stabilize a negative charge through resonance.

3. **Evaluate Inductive Effects**:
- The inductive effect (I effect) refers to the electron-withdrawing or electron-donating effects of substituents. Electron-withdrawing groups (like NO2) stabilize negative charges, while electron-donating groups (like CH3) destabilize them.

4. **Compare Stability**:
- Based on the resonance and inductive effects, compare the stability of the anions. For example:
- NO2^- > CN^- > Cl^-
- This order indicates that NO2^- is the most stable due to resonance stabilization.

5. **Analyze Each Option**:
- Go through each option provided in the question and apply the above principles to determine if the stability order is correct.

6. **Conclusion**:
- After analyzing all options, conclude which stability orders are correct based on your evaluations.
