Question

a. Draw the mechanism (in individual steps) of hydration for 2-methyl-2-butene using phosphoric acid.

b. Is the product Markovnikov or anti-Markovnikov?

c. Is the reaction prone to rearrangement? Is a hydride or methyl shift possible?

d. Will the reaction stereospecific or will it give a racemic mixture?

Answer 1

Solution given below :-

b) Reaction follow markovnikav rule and more stable carbocation is formed and H2O attack on carbon having less number of hydrogens.

c) No rearrangement occur in above reaction but if any reaction unstable carbocation is formed then it will rearrange to more stable carbocation.

d) It is regio selective and give product according to markounikov rule.

c) No rearrangement occur in above reaction but if any reaction unstable carbocation is formed then it will rearrange to more stable carbocation.
