Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Treatment of bromine water with propene yields 1-bromopropan-2-ol. Reason (R) : Attack of water on bromonium ion follows Markovnikov rule and results in 1-bromopropan-2-ol. In the light of the above statements, choose the most appropriate answer from the options given below :

Options

  1. ABoth (A) and (R) are true but (R) is NOT the correct explanation of (A).
  2. B(A) is false but (R) is true.
  3. CBoth (A) and (R) are true and (R) is the correct explanation of (A ).
  4. D(A) is true but (R) is false.

Correct answer

C. Both (A) and (R) are true and (R) is the correct explanation of (A ).

Step-by-step solution

Markovnikov's rule of addition : In an electrophilic addition reaction to alkenes and alkynes the electrophile attacks in such a way that a more stable carbocation intermediate is formed on which nucleophile attacks in the next step.
