Q
Q: What type of reaction occurs when phenol is treated with sodium hydroxide?
Solution:
Phenol reacts with sodium hydroxide in a nucleophilic substitution reaction to form phenoxide ion.
Steps: 6
Show Steps
Step 1: Understand that phenol is a compound that contains a hydroxyl group (-OH) attached to a benzene ring.
Step 2: Recognize that sodium hydroxide (NaOH) is a strong base that can react with phenol.
Step 3: When phenol is mixed with sodium hydroxide, the hydroxide ion (OH-) from NaOH acts as a nucleophile.
Step 4: The nucleophile (OH-) attacks the hydrogen atom of the hydroxyl group in phenol.
Step 5: This results in the removal of the hydrogen atom from phenol, forming a phenoxide ion (C6H5O-).
Step 6: The overall reaction can be summarized as phenol + sodium hydroxide → phenoxide ion + water.
