Question
### Reaction Completion and Product Identification

Please complete the reactions below. For reaction "b," add a substrate. For the other reactions, write down the major product(s).

**Hints:** For "e," hydride from LiAlH₄ serves as the nucleophile in the first step.

#### Reaction Details

**a.**
- **Starting Material:** Cyclohexanol
- **Reagent/Conditions:** H₂SO₄, 180°C
- **Expected Reaction:** Dehydration to form cyclohexene.

**b.**
- **Starting Material:** Phenyl lithium
- **Reagents:**
  1. Lithium reagent
  2. H₃O⁺
- **Expected Process:** Nucleophilic addition followed by protonation.

**c.**
- **Starting Material:** Sodium phenoxide
- **Reagent:** CH₃Br
- **Expected Reaction:** Williamson ether synthesis to form anisole (methoxybenzene).

**d.**
- **Starting Material:** 3,3-Dimethyl-1-butanol
- **Reagent:** HBr
- **Expected Reaction:** Conversion to alkyl bromide through substitution.

**e.**
- **Starting Material:** Cyclopentanone
- **Reagents:**
  1. LiAlH₄, (CH₃CH₂)₂O
  2. H₃O⁺, H₂O
- **Expected Reaction:** Reduction to form cyclopentanol.

Note: The reactions detailed above are fundamental transformations often encountered in organic chemistry, with specific emphasis on mechanisms like dehydration, nucleophilic addition, Williamsons' ether synthesis, and reductions involving hydrides.
