Alcohols, Phenols and Ethers: NEET questions with solutions
NEET tests the acidity order of alcohols and substituted phenols, the Lucas test, oxidation products of primary, secondary and tertiary alcohols, Kolbe and Reimer-Tiemann reactions, Williamson synthesis and how HI cleaves ethers. Marks are lost on the direction of ether cleavage and on which alkyl halide suits Williamson synthesis.
