Statement 1: The B-F bond length in \( \mathrm{BF}_{3} \) is not
\( \mathrm{P} \)
identical with that in \( \mathrm{BF}_{4}^{-} \)because
W
Statement 2: Back bonding is involved in \( \mathrm{BF}_{4}^{-} \)but not in \( \mathrm{BF}_{3} \).
(1) Statement-1 is true, statement-2 is true and statement-2 is correct explanation for statement-1.
(2) Statement- 1 is true, statement- 2 is true and statement- 2 is NOT the correct explanation for statement-1.
(3) Statement- 1 is true, statement- 2 is false.
(4) Statement-1 is false, statement-2 is true.
