Question
**Problem Statement:**

Based on the partial reaction mechanism shown below and the reaction details, which of the following is the expected product of this reaction?

**Reaction Mechanism:**

The mechanism begins with a hydroxonium ion (H₃O⁺) where the oxygen donates a lone pair to a carbon in the alkene chain, forming a carbocation intermediate. A subsequent step involves the addition of water (H₂O).

**Answer Choices:**

1. **Choice A:** 3-buten-1-ol  
   Structure: A four-carbon chain with an alcohol group (OH) attached at the terminal carbon.

2. **Choice B:** 2-buten-1-ol  
   Structure: A carbocation intermediate is shown with a positive charge on oxygen, forming a five-membered ring.

3. **Choice C:** 2-penten-2-ol  
   Structure: An alcohol group (OH) attached to the second carbon of a five-carbon chain with a double bond.

4. **Choice D:** 4-penten-1-ol methyl ether   
   Structure: A five-carbon chain with an ether group (OCH₃) at the terminal end.

5. **Choice E:** 2-penten-1-ol  
   Structure: A five-carbon chain with an alcohol group (OH) attached at the terminal carbon.

**Explanation of Diagrams:**

The diagrams represent different organic structures that could potentially be products of the reaction. Each structure contains a different placement or form of functional groups such as alcohols and ethers, and one includes a resonance-stabilized carbocation. The choice of the correct product will depend on understanding the mechanism and stability of intermediates.
