Draw the major organic product formed in the following reaction.
Concepts and reason
Alcohols undergo a dehydration reaction when the react with concentrated acids in the presence of heat. Product formation is undergone with the help of an elimination reaction.
When alcohols undergo a reaction with strong acids (like H2SO4, H3PO4) in the presence of heat, it forms an alkene product with the elimination of water. It undergoes 1, 2 –elimination to form an alkene.
The alcoholic oxygen undergoes protonation with the help of a lone pair of electrons and makes it a better leaving group. Then the leaving group cleaves and forms a carbocation intermediate which is the rate determining step for this reaction.
The methyl group is rearranged and forms carbocation in the second carbon. Then the lone pair of oxygen electrons abstracts a proton and forms an alkene product by stabilizing the carbocation.
