Vedclass · Accepted Answer

The unusual shortness and strength of the $B-F$ bond cannot be explained by $p\pi-p\pi$ interaction between boron and fluorine.

Vedclass · Answer

(C) In $BF_{3}$,the boron atom is $sp^{2}$ hybridized and has an empty $p$-orbital.Fluorine atoms have lone pairs in their $2p$-orbitals.There is a back-bonding effect where fluorine donates electron density into the empty $p$-orbital of boron,creating a $p\pi-p\pi$ bond.This back-bonding gives the $B-F$ bond partial double bond character,making it shorter and stronger than a typical single bond.Therefore,the statement that this interaction cannot explain the shortness and strength of the bond is incorrect.

Which of the following statements is incorrect regarding the $B-F$ bond in $BF_{3}$?
