What Happens when Phenol is Treated with Chloroform - Nepali Educate

Question:

What happen when phenol is treated with chloroform in presence of base.
Prepare DDT , Benzene from chlorobenzene ,2 chloroacetophenone.
Why phenol is more acidic than alcohol ? Give reason with structure.

Question is collected from our Telegram Group.

Solution:

Phenol in presence of base (sodium hydroxide) reacts with chloroform to form salicyladehyde. The reaction is known as Reimer-Tiemann reaction.

Reaction

DDT From Chlorobenzene:
DDT is prepared y heating chloral and cholorobenzene in 1:2 ratio in presence of Conc. H₂SO₄. Reaction:
Benzene from Chloro Benzene:
On reduction of chlorobenze with Nickel metal and Al/NaOH, benzene is formed. Reaction:
2-chlaroacetophenone Reaction:
Phenol is more acidic than alcohol due to the presence of an electron withdrawing group (-OH) attached directly to the aromatic ring. This group stabilizes the conjugate base formed after losing a proton, making it easier to donate a proton.
