The alcohol with tertiary hydroxyl group will undergo dehydration most easily.
Explanation:
- The alcohol has the alkyl chain and the hydroxyl group attached to it.
- If the hydroxyl group is attached to carbon with 2 hydrogen then it's 1° alcohol.
- If the hydroxyl group is attached to carbon with 1 hydrogen then it's 2° alcohol.
- If the hydroxyl group is attached to carbon with 0 hydrogen then it's 3° alcohol.
- When the alcohol undergoes dehydration, the hydroxyl group undergoes protonation.
- This leads to elimination of the water molecule to form the Carbo cation.
- The stability of carbocation is in the order of 3°>2°>1°.
- So the tertiary alcohol undergoes dehydration most early.
