WILLIAMSON SYNTHESIS

WILLIAMSON SYNTHESIS

Williamson synthesis is a widely used method in organic chemistry for the preparation of ethers. It involves the reaction between an alkyl halide (R-X) and a deprotonated alcohol (R’-O^-) to form an ether (R-O-R’). SCROLL DOWN TO THE BOTTOM OF…

ACIDITY OF PHENOLS

ACIDITY OF PHENOLS

Acidity of Phenols: Phenols are organic compounds that contain a hydroxyl group (-OH) attached to an aromatic ring. The presence of the hydroxyl group makes phenols weak acids. Compared to alcohols, phenols exhibit greater acidity due to the resonance stabilization…
