NEET Chemistry (general) Assertion Reason Question
Type: Assertion Reason-assertion-Medium-Class 12
Assertion (A): Alcohols can be obtained in excellent yield by hydroboration–oxidation of alkenes. | Reason (R): The addition of borane to the double bond takes place in such a manner that the boron atom gets attached to the sp2 carbon carrying fewer hydrogen atoms.
A
Both A and R are true and R is the correct explanation of A.
B
Both A and R are true but R is not the correct explanation of A.
C
A is true but R is false.
D
A is false.
Correct Answer
Option C
Detailed Explanation
The assertion is true as hydroboration–oxidation yields alcohols in high amounts. However, the reason is incorrect because borane adds to the sp2 carbon with more hydrogen atoms, contrary to Markovnikov's rule.
