Given below are two statements : one is labelled as Assertion (A)...
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 :
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
- ABoth (A) and (R) are true but (R) is NOT the correct explanation of (A).
- B(A) is false but (R) is true.
- CBoth (A) and (R) are true and (R) is the correct explanation of (A ).
- 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.
