Chemistry · EQUILIBRIUM
हिन्दीGiven below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): \( \text{BF}_3 \) acts as an acid according to the Lewis concept despite having no protons. Reason (R): Species that accept an electron pair act as Lewis acids. In the light of the above statements, choose the correct answer from the options given below:
Correct answer · Option 2
Both (A) and (R) are true but (R) is NOT the correct explanation of (A).
Explanation
Both (A) and (R) are true statements. However, (R) is just the definition of a Lewis acid; the specific explanation for BF3 being a Lewis acid is that the central boron atom is electron-deficient with an incomplete sextet.
