The image depicts a chemical reaction mechanism involving bromine (Br). **Description:** 1. **Structures and Symbols:** - A bromine atom is bonded to a cyclohexane ring. The bromine atom has a positive charge (Br⁺) and is depicted with three lone pairs of electrons. - Another bromine atom, which is negatively charged (Br⁻), is shown with four lone pairs of electrons. 2. **Arrows:** - A blue curved arrow points from one of the lone pairs of the negatively charged bromine towards the positively charged bromine, indicating an intramolecular or intermolecular electron transfer. 3. **Direction:** - Bold black arrows point vertically downwards, suggesting the direction of the chemical process or mechanism. This mechanism might represent a nucleophilic attack by the bromide ion on the positively charged bromine, common in halogen addition reactions or substitutions.

Curved arrows are used to illustrate the flow of electrons. Follow the curved arrows and draw the products of the following reaction. Include all lone pairs and charges as appropriate. Ignore inorganic byproducts. **Explanation of Diagram:** 1. **Initial Structure:** - A cyclohexane ring with two bromine atoms, each with lone pairs represented by dots. - Curved arrows are shown, indicating an electron movement from the lone pair on the top bromine to form a bond with the adjacent bromine. 2. **Reaction Process:** - A vertical arrow points downward to the second diagram, which represents the product of the reaction. 3. **Product Structure:** - The cyclohexane ring is now attached to a bromine ion (Br⁺), which has lost a lone pair, indicated by a positive charge. - Another bromine atom with three lone pairs and a negative charge (Br⁻) is nearby, indicating the formation of a bromonium ion intermediate. This exercise demonstrates how to follow electron flow in organic reaction mechanisms through the use of curved arrows.
