Vedclass · Answer

(C) In $BF_3$,the central atom is Boron $(B)$.Boron has $3$ valence electrons and forms $3$ $\sigma$-bonds with $3$ Fluorine atoms.Number of lone pairs $(lp)$ on central atom = $0$.Steric number = (Number of $\sigma$-bonds) + (Number of lone pairs) = $3 + 0 = 3$.$A$ steric number of $3$ corresponds to $sp^2$ hybridization.The total number of electrons around the central Boron atom is $3 	imes 2 = 6$ electrons (due to $3$ covalent bonds).Thus,the hybridization is $sp^2$ and the number of electrons is $6$.

$BF_3$ is a planar and electron-deficient compound. The hybridization and the number of electrons around the central atom,respectively,are:
