During electrolysis which anion migrates towards anode so as to produce `2,3-`dimethyl butane

Options

A. `CH_(3)-CH_(2)-COO^(-)`
B.
C. `CH_(3)-underset(CH_(3))underset(|)(C)HCOO^(-)`
D. `CH_(3)COO^(-)`

Explanation

To determine which anion migrates towards the anode during electrolysis to produce 2,3-dimethylbutane, we can follow these steps:

### Step 1: Identify the target product
The target product is 2,3-dimethylbutane. This compound has the following structure:

```
CH3
|
CH3 - C - C - CH3
|
CH3
```

### Step 2: Determine the precursor molecules
To synthesize 2,3-dimethylbutane, we need to identify the precursor molecules. The precursor for this compound can be derived from 2 molecules of 2-butanol (or a similar compound). The molecular formula for 2-butanol is CH3-CH(OH)-CH2-CH3.

### Step 3: Electrolysis process
During electrolysis, we need to convert the precursor into a suitable anion that can migrate towards the anode. The electrolysis of 2-butanol can lead to the formation of a carbanion or a suitable anion.

### Step 4: Identify the anion
The anion that will migrate towards the anode is the one that can lead to the formation of the desired alkane. In this case, the anion that will migrate is the one derived from the deprotonation of 2-butanol, which can be represented as:

\[ \text{CH}_3\text{CH}(\text{C}O^{-})\text{CH}_3 \]

This indicates that the anion is the carboxylate form, specifically:

\[ \text{CH}_3\text{CH}(\text{C}O^{-})\text{CH}_3 \]

### Step 5: Conclusion
Thus, the anion that migrates towards the anode during the electrolysis to produce 2,3-dimethylbutane is:

\[ \text{CH}_3\text{CH}(\text{C}O^{-})\text{CH}_3 \]

### Final Answer
The anion that migrates towards the anode is \( \text{CH}_3\text{CH}(\text{C}O^{-})\text{CH}_3 \).
