Amongst the following phenols which is most acidic? Lucas reagent reacts fastest with tertiary alcohol. The reaction between alcohol and carboxylic acids is called, a) Esterification              b) Hydrolyais, c) Saponification            d) Hydrogenation, 34. Phenol has activating (electron releasing)-OH group and bromine water supplies Br+ ion easily, hence under such conditions reaction does not stop at monobromo or dibromo stage but a fully brominated (2,4,6,-tribromophenol) compound is the final product. (3) $\mathrm{C}_{6} \mathrm{H}_{5} \mathrm{Br}+\mathrm{CH}_{2}=\mathrm{CH}-\mathrm{CH}_{2}-\mathrm{ONa}$ All MCQs have been carefully developed for all types of students, you can download in PDF Chemistry Alcohol Phenol and Ether Chapter wise MCQs question bank with answers and use them for further studies. Phenol on treatment with $\mathrm{CO}_{2}$ in the presence of NaOH followed by acidification produces compound X as the major product. Alcohols Phenols And Ethers Questions And Answers, Methyl alcohol can be distinguished from ethyl alcohol using, C)                 Sodium hydroxide and iodine, Methyl alcohol does not respond to Iodoform Test, How can we get ether by catalytic dehydration, and O has a pleasant odour with a boiling point of, a colourless gas is produced which decolourises bromine water and alkaline, One mole of this gas also takes one mole of. The original compound showed these properties also: Due to greater electronegativity of sp2-hybridizad carbon atoms of the benzene ring,    di–aryl ethers are not attacked by nucleophiles like I−, A) Phenol + dimethyl sulphate in presence of a base, B) Sodium phenoxide is treated with methyl iodide, D) Reaction of methyl magnesium iodide with phenol, Phenol has active (acidic) hydrogen so it reacts with CH3MgI to give CH4, and not anisole C6H5OH+CH3MgI→CH4+C6H5OMgI. 2 g of phenol require Br2=480/94×2=10.22g. 68. This method involves the treatment of alkyl halide with sodium or potassium salt of alcohol or phenol. Thus the stability order of the four carbocations and reactivity of their parent alcohols will be IV > III > II > I.
