Give the product obtained from the oxidation of the following compounds with acidic `K_(2)Cr_(2)O_(7).`
`a.` Cyclobutene , `b. 1-`Methyl cyclobutene
`c.` `1,2-` Dimethyl cyclobutene

Explanation

To solve the problem of determining the products obtained from the oxidation of the given compounds with acidic \( K_2Cr_2O_7 \), we will analyze each compound step by step.

### Step 1: Oxidation of Cyclobutene
1. **Structure of Cyclobutene**: Cyclobutene is a four-membered cyclic alkene with a double bond.
2. **Oxidation Reaction**: When cyclobutene is oxidized with acidic \( K_2Cr_2O_7 \), the double bond is oxidized to form carboxylic acid groups.
3. **Product Formation**: The double bond between the two carbon atoms will break, and each of these carbon atoms will be converted into a carboxylic acid group (\(-COOH\)).
4. **Final Product**: The resulting compound is butane-1,4-dioic acid (succinic acid).
