Question
CH C=CH2 CHy The net result of the elimination reaction of an alcohol is the loss of water (dehydration) with the formation of an alkene. As with alkyl halides, the rate of reaction relative to the substrate is 32° >>> 1 Which of the following alcohols co most easily dehydrated? hat is the product of the reaction of tert-butyl alcohol with 20% sulfure acid solution? 2-methylpropane C. 2-butanone B. isobutane D. 2-methylpropene 0. What would be the formula of the major product in the dehydration reaction below? H* +H,o Chl'CH-CH2-CH2-CH, CH,-CH-CH2-CH2-CH, B. CH-CH-CH-CH2-CH C. CH-CO-CH CH CH I. What would be the major product of the dehydration reaction shown below? OH CH3 D. B. A. CHy CH3 CH3 CHy 12. The reaction of ethanol with a strong acid yields D. 1,1-ethanediol A. ethene B. ethane C. 1,2-ethanediolExplanation / Answer
4-8. The answer is A, (CH3)3-OH. As explained above the carbocation formed by 3o alcohol is more stable, hence the dehydration takes place more rapidly as compared to 2o and 1o alcohols.
