**CHEM 120 - Essentials of Organic Chemistry**

**Recitation 6**

**3. [Multiple Choice] Choose an alcohol best suitable for this reaction.**

\[ \text{?} \rightarrow \text{Reacts with } \text{K}_2\text{Cr}_2\text{O}_7 \rightarrow \text{Product} \]

The reaction involves an alcohol transformed into a carboxylic acid with a carbonyl group, \(\text{C(C=O)CH}_3\).

**Options:**

A. Structure:  
- CH3CH2CH(OH)

B. Structure:  
- CH3CH(OH)CH3

C. Structure:  
- HOCH2CH(OH)CH2OH

D. Structure:  
- CH3C(OH)(OH)CH3

**Explanation:**  
The diagram shows four potential alcohols labeled A, B, C, and D. The reaction uses potassium dichromate (\(\text{K}_2\text{Cr}_2\text{O}_7\)) as an oxidizing agent to produce a carboxylic acid from an alcohol. Your task is to choose the one that will produce the desired carboxylic product with the molecular formula including the \(\text{C(C=O)CH}_3\) group.

Expert Solution
Step 1

Chromic acid is a fairly straight forwed reagent. It oxidizes primary alcohol to carboxylic acids and secondary alcohol to be ketones. It will also oxidize aldehydes to carboxylic acids.
