Question
Identify the major product X obtained in the following reaction.
2,3-dimethylbutan-2-olConc. H2SO4−−−−−−−−→X
Identify the major product X obtained in the following reaction.
2,3-dimethylbutan-2-olConc. H2SO4−−−−−−−−→X
Open in App
Solution
The correct option is A
Dehydration of alcohol occurs when the reaction proceeds in the presence of sulphuric acid.
(CH3)2HC−C(OH)(CH3)2Conc. H2SO4−−−−−−−−→(CH3)2C=C(CH3)2+(CH3)2CHC(CH3)=CH2
2,3-dimethylbut-2-ene and 2,3-dimethylbut-1-ene are formed but 2,3-dimethylbut-2-ene will be the major product according to Saytzeff.
Hence option (a) is correct.
