Vedclass · Accepted Answer

The unusual shortness and strength of the $B-F$ bond can be explained by $p\pi - d\pi$ interaction between boron and fluorine.

Vedclass · Answer

(D) In $BF_3$,boron is $sp^2$ hybridized and the molecule is planar. Due to the vacant $2p$ orbital on the boron atom and the filled $2p$ orbitals on the fluorine atoms,there is a $p\pi - p\pi$ back-bonding (back-donation) from $F$ to $B$. This gives the $B-F$ bond partial double bond character,making it shorter and stronger than a typical single bond. Therefore,the statement that it is explained by $p\pi - d\pi$ interaction is incorrect,as boron does not have $d$-orbitals.

$Bond$	$E_{diss} (kJ \ mol^{-1})$
$C-A$	$240$
$C-B$	$328$
$C-C$	$276$
$C-D$	$485$

Which of the following statements is incorrect regarding the $B-F$ bond in $BF_3$?
