Question
**Question 2:** **Diagram 1:** - The illustration shows a chemical reaction where a pentagon-shaped molecule with an oxygen atom carrying a pair of dots (lone pair) interacts with boron trifluoride (BF₃). - The oxygen atom acts as a base, donating its lone pair to the boron atom, which is electron-deficient, thus acting as an acid. - An arrow indicates the movement of the lone pair from the oxygen to the boron atom, forming a coordinate bond. - The product shows the oxygen atom bonded to BF₃, with a negative charge on the oxygen. **Diagram 2:** - This part of the diagram presents another step in the reaction, possibly illustrating the resonance or further stabilization. - The initial pentagon molecule is shown again interacting with BF₃, leading to a new configuration where the charge distribution might differ. - The final product indicates a positive charge on the pentagon structure and a negative charge on the BF₃ side. These diagrams likely accompany explanations on Lewis acid-base reactions, emphasizing coordination chemistry involving electron pair donation.
