## Educational Resource on Reaction Mechanisms

### Reaction Schemes

#### 1.
The first reaction depicts a Grignard reaction:

- A phenylmethyl alcohol reacts with methyl magnesium iodide in dry ether to produce a phenyl methyl ketone, magnesium iodide (MgI), and methane (CH₄).

#### 2.
The second reaction shows an acid-catalyzed etherification:

- Cyclohexanol reacts in aqueous H₂SO₄ to form cyclohexene.

### Mechanism Key

- **a** = Proton transfer
- **b** = Lewis acid/base
- **c** = Electrophilic addition
- **d** = E1 Elimination
- **e** = E2 Elimination
- **f** = S<sub>N</sub>1 Nucleophilic substitution
- **g** = S<sub>N</sub>2 Nucleophilic substitution

### Instructions

The reactions above illustrate the synthesis or reactions of alcohols and ethers. Identify which reaction mechanism each transformation proceeds through using the letters **a - g**.
