Vedclass · Answer

(D) $BCl_3$ is a covalent molecule with a planar triangular geometry.It is electron-deficient,having only $6$ electrons in the valence shell of Boron,hence it acts as a strong Lewis acid.Due to the back-bonding ($p\pi-p\pi$ back-donation) from $Cl$ to $B$,the $B-Cl$ bond acquires some double-bond character.This makes the $B-Cl$ bond length shorter than a pure single bond.Therefore,the statement that all $B-Cl$ bonds are longer than a single bond is incorrect.

Which of the following statements is incorrect regarding $BCl_3$?
