Question

Can you please explain mechanistically the steps of this reaction? For example, list the importance or role of each compound in this reaction.  

Explain in 1-2 paragraphs how this reaction takes place, and steps.  

In the current experiment, we will use a different electrophile (the tert-butyl cation) to alkylate 1,4-dimethoxybenzene. This is a Friedel-Crafts Alkylation reaction.

**Chemical Reaction:**
- **Reactants:**
  - 1,4-dimethoxybenzene with molecular structure showing a benzene ring with two methoxy groups (OCH₃) attached at positions 1 and 4.
  - Tert-butyl alcohol \((CH₃)₃COH\)

- **Catalyst:**
  - Acetic acid (\(CH₃COOH\)) and sulfuric acid (\(H₂SO₄\))

- **Product:**
  - A benzene ring substituted with two methoxy groups (OCH₃) and two tert-butyl groups \((CH₃)₃C\).

The diagram illustrates the process of substituting hydrogen atoms in a benzene ring of 1,4-dimethoxybenzene with tert-butyl groups through electrophilic substitution, a characteristic of Friedel-Crafts Alkylation.

Expert Solution
Step 1: Friedel Craft's alkylation

Friedel Craft's alkylation is a type of electrophilic substitution reaction. In the given reaction an alcohol and acid are taken to form the electrophile. This electrophile is then attacked by the ring and it then replaces one hydrogen to give the final product. The mechanism of electrophilic substitution reaction generally involves 3 steps.
