C. basicity order
D. acidity order

Answer

To solve the question regarding the correct orders of acidity and basicity for the given compounds, we will analyze the structures and their effects on acidity and basicity step by step.

### Step 1: Analyze the Structures
We have two main structures to consider:
1. **Structure A**: Contains a carboxylic acid group (COOH) with two methyl (CH3) groups at the ortho positions and a nitro (NO2) group at the para position.
2. **Structure B**: Contains a carboxylic acid group (COOH) with two nitro (NO2) groups at the meta positions and a hydroxyl (OH) group at the para position.

### Step 2: Assess Acidity
To determine the acidity of these compounds, we need to consider the stability of the conjugate base formed after deprotonation (removal of H+).

- **For Structure A**: The presence of two bulky CH3 groups at the ortho positions creates steric hindrance, which affects the resonance stabilization of the negative charge on the conjugate base. The negative charge can be delocalized over the oxygen atoms, but the steric hindrance reduces the effective resonance stabilization.

- **For Structure B**: The nitro groups at the meta positions do not provide resonance stabilization to the conjugate base as effectively as the ortho groups in Structure A. However, the presence of the hydroxyl group can stabilize the negative charge through resonance.

### Step 3: Compare Acidity
- The steric hindrance in Structure A reduces the resonance stabilization of the negative charge, making it less acidic compared to Structure B, where the negative charge can be more effectively stabilized by resonance with the hydroxyl group.

### Conclusion on Acidity
Thus, the order of acidity is:
\[ \text{Acidity: A < B} \]

### Step 4: Assess Basicity
Now, let's consider the basicity of the compounds:
- **Aromatic amines** (like Structure A) have their lone pair of electrons involved in resonance with the aromatic ring, making them less available for protonation.
- **Aliphatic amines** (like Structure B) have their lone pair of electrons more available for donation since they are not involved in resonance.

### Conclusion on Basicity
Therefore, the order of basicity is:
\[ \text{Basicity: Aliphatic amines > Aromatic amines} \]

### Final Answer
The correct orders are:
- Acidity: \( B > A \)
- Basicity: \( \text{Aliphatic amines} > \text{Aromatic amines} \)
