**Title: Understanding Reaction B**

**Instructions:** Draw the product of Reaction B.

**Reaction Details:**

- **Reagents:** The reaction involves an excess of hydrogen gas (H₂) and a palladium (Pd) catalyst.
- **Reactant:** The reactant is a cyclooctyne, which is an eight-carbon ring containing a triple bond.

**Diagram Explanation:**

- **Structure:** The diagram shows a simple representation of a cyclic structure with a triple bond, indicating the location of the alkynyl group within the cyclooctyne.
- **Reaction Mechanism:** The hydrogenation process involves the addition of hydrogen across the triple bond, facilitated by the palladium catalyst, converting the alkyne into an alkane.
- **Graphical User Interface (GUI) Elements:** 
  - Users have options to select, draw, and modify structural elements like rings (spanning from alkyne to fully saturated ring structures).
  - Buttons provided for undo, redo, and zoom functions facilitate easy manipulation of the diagram. These elements help users visualize the chemical reaction process, offering an interactive learning experience.

**Objective:** Complete the reaction by drawing the final product, ensuring that the alkyne is fully reduced to an alkane, illustrating your understanding of the hydrogenation process in the presence of a catalyst.
