* Cyclohexanol is a secondary alcohol.
* Dehydration is the removal of water (H₂O).
* Mechanism: The reaction proceeds via an E1 mechanism, involving the formation of a carbocation intermediate.
The two isomers formed are:
1. Cyclohexene: This is the major product, formed by the removal of a hydrogen atom from the carbon adjacent to the hydroxyl group.
2. 1-Methylcyclopentene: This is a minor product, formed by a less stable carbocation rearrangement before the loss of water.
