**Title: Understanding the Mechanism of Chemical Reactions through Arrow Drawing**

**Section: Reaction Overview**

**Drawing Arrows**

This section of the diagram focuses on understanding how to draw mechanisms using curly arrows, which indicate the movement of electron pairs in chemical reactions.

**Reagents and Conditions:**

- **Reagents:** Sodium methoxide \((\text{CH}_3)_3\text{ONa}\), Methanol \((\text{CH}_3)_3\text{OH}\)
- **Condition:** Heat

**Reaction Scheme Explanation:**

The reaction involves a transformation under heat using sodium methoxide and methanol. The diagram showcases several molecular structures interacting:

1. **Left Structure:** A tert-butyl group with a hydroxyl group depicted with lone pairs on the oxygen.
2. **Middle Structure:** An alkene (carbon-carbon double bond) with a bromide ion indicated with lone pairs and a negative sign.
3. **Right Structure:** A potassium cation next to a methoxide ion with lone pairs depicted.

These structures illustrate the key players in the reaction, emphasizing electron flow and the resulting formation of products through the reaction mechanism. The curly arrows (not shown in the image but conceptually needed) would indicate electron pair movements, leading to bond formations and breakages essential to understanding the chemical pathway.

The image presents a reaction diagram illustrating the conversion of a brominated alkane to an alkoxide and an alkene. The structures and components in the image are as follows:

1. **Reactant**
   - **2-Bromo-2,3-dimethylbutane**: This is the starting material located at the top left. It has a six-carbon chain with bromine (Br) attached to the second carbon. There are methyl groups (CH₃) on the second and third carbons.

2. **Base**
   - **Potassium tert-butoxide (KO⁺)**: The base is shown with a positively charged potassium ion (K⁺) and a tert-butoxide ion (O⁻) presented in the top right. The tert-butoxide ion consists of a central oxygen atom bonded to a tert-butyl group, noted by the three methyl (CH₃) groups.

3. **Product**
   - **tert-Butanol**: This is the product formed by the action of the base on the alkyl halide, shown at the bottom left. It has a central oxygen (OH) group bonded to a tert-butyl group.

**Reaction Overview:**
The reaction showcases a nucleophilic substitution or elimination reaction, where the potassium tert-butoxide acts as a base to deprotonate the surrounding medium or engage with the substrate, leading to the formation of tert-butanol and a possible elimination product, an alkene.

This diagram is useful in organic chemistry education to illustrate base-induced transformations and product formation from a brominated alkane using a strong base like potassium tert-butoxide.
