The correct statement is
- A \( \mathrm{BF}_{3} \) is the strongest Lewis acid among the other boron halides.
- B \( \mathrm{BI}_{3} \) is the weakest Lewis acid among the boron halides.
- C There is maximum \( p \Pi-p_{\Pi} \) back bonding in \( B F_{3} \)
- D There is minimum \( p_{\Pi}-p_{I} \) back bonding in \( B F_{3} \)
Answer & Solution
Correct Answer
(C) There is maximum \( p \Pi-p_{\Pi} \) back bonding in \( B F_{3} \)
Step-by-step Solution
Detailed explanation
There is maximum \( p \pi-p \pi \) back bonding in \( B F_{3} \) due to identical size of \( 2 p^{-} \)orbitals of \( B \) and \( F \)
