Draw the structures of organic compounds A and B. Omit all byproducts.

**Title: Synthesis of an Alcohol from Organic Compounds A and B**

In this diagram, the task involves identifying and drawing the structures of two organic compounds, labeled as Compound A and Compound B, in a synthetic pathway. All byproducts are to be omitted in this process.

**Synthetic Pathway:**

1. **Stage 1: Formation of Compound B**
   - **Reactants:** Compound A reacts with magnesium (Mg) in the presence of ether. This is typically indicative of a Grignard reaction where an organomagnesium compound is formed.
   - **Product:** Compound B

2. **Stage 2: Conversion to Final Product**
   - **Reactants:** Compound B reacts first with acetaldehyde and then with water (H₂O) in a two-step reaction.
   - **Final Product Structure:** The product is an alcohol with the following structure:
     - A four-carbon chain with an OH group on the second carbon, indicating a secondary alcohol.

**Chemical Reaction Explanation:**

- The Grignard reagent formed from Compound A reacts with acetaldehyde. This nucleophilic addition results in the formation of a secondary alcohol after the addition of water.
- The diagram illustrates a linear carbon chain with the OH group attached to the second carbon, typically depicted with the condensed formula of the alcohol.

This sequence demonstrates how organometallic chemistry can be utilized for synthesizing alcohols. Understanding the formation and application of Grignard reagents is crucial in organic synthesis, providing valuable insights into creating complex organic molecules.
