Chemistry · CHEMICAL BONDING AND MOLECULAR STRUCTURE

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Kössel and Lewis postulated that noble gases have little chemical activity because their atoms possess a stable outer shell configuration of eight electrons. Reason (R): In chemical combination, atoms achieve stable noble gas electronic configurations either by sharing or by transferring valence electrons. In the light of the above statements, choose the correct answer from the options given below:

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