Question

Hydration of propene in presence of dilute sulphuric acid

Answer 1

Answer:

Hydration of propene in the presence of dilute sulphuric acid will result in the formation of a carbocation as an intermediate. ... Thus, the hydroxide ion will attach to the secondary carbon of propene. Therefore, according to Markonikov's rule regioselectivity will be favoured over stereoselectivity.

\cdot Reaction is proceeded by stable carbocation intermediate due to protonation and Hence, Regioselectivity is decided by Markovinov's Rule.

\cdot Reaction is not stereoselective.
