NEET Chemistry pH & Buffer Solutions Assertion Reason Question
Assertion (A): BF3 can act as an acid without containing a proton. | Reason (R): BF3 is an electron-deficient species that can accept a lone pair of electrons.
Both A and R are true, and R is the correct explanation of A.
Both A and R are true, but R is not the correct explanation of A.
A is true, but R is false.
A is false.
Correct Answer
Detailed Explanation
