Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R)Assertion (A): Boron is unable to form \(BF_6^{3+}\)Reason (R): Size of B is very small.In the light of the above statements, choose the correct answer from the options given below:(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 but (R) is true

Answer»

Correct option is (B) Both (A) and (R) are true but (R) is not the correct explanation of (A)

Assertion (A): True

Reason (R): True but not correct explanation.

Correct explanation: Expansion of octet not possible for ‘B’.

ans  is.  b.


 since boron can't exhibit+6 O.S. even in the excited state so BF6 can't exist.


also the size of B is small as size decrease along period. but this fact has nothing to do with formation of BF6. hence not correct explanation
