Which of the following can give aldehyde by the oxidation with Jones reagent?

Options

A.
B. `CH_(2)=CH-CH_(2)OH`
C. `H_(3)C-underset(CH_(2)) underset(|) overset(CH_(3)) overset(|)(C)-CH_(2)OH`
D.

Explanation

To determine which compounds can give aldehydes upon oxidation with Jones reagent, we need to consider the nature of the compounds provided in the options. Jones reagent, which is a solution of chromium trioxide (CrO3) in dilute sulfuric acid, is commonly used to oxidize alcohols.

### Step-by-Step Solution:

1. **Identify the Types of Alcohols**:
- First, we need to identify whether the compounds in the options are primary (1°), secondary (2°), or tertiary (3°) alcohols.
- Primary alcohols can be oxidized to aldehydes, while secondary alcohols can be oxidized to ketones. Tertiary alcohols do not undergo oxidation to aldehydes or ketones.

2. **Analyze the Options**:
- For each option, determine its structure and classify it as primary, secondary, or tertiary alcohol.
- Example:
- If an option is a primary alcohol (like ethanol), it can be oxidized to an aldehyde (like acetaldehyde).
- If an option is a secondary alcohol (like isopropanol), it will be oxidized to a ketone (like acetone) instead of an aldehyde.
- If an option is a tertiary alcohol (like tert-butanol), it will not be oxidized to any carbonyl compound.

3. **Apply the Oxidation Reaction**:
- For each primary alcohol identified, write the oxidation reaction with Jones reagent to show the formation of the corresponding aldehyde.
- Example:
- Ethanol (C2H5OH) + Jones reagent → Acetaldehyde (CH3CHO) + H2O

4. **Conclusion**:
- List all the compounds that can be oxidized to aldehydes with Jones reagent based on the analysis.
- Only primary alcohols will yield aldehydes upon oxidation.

### Final Answer:
The compounds that can give aldehydes upon oxidation with Jones reagent are the primary alcohols from the options provided.
