$SnCl_4$

Vedclass · Answer

(D) The octet rule states that atoms tend to form bonds such that they have $8$ electrons in their valence shell. $BH_3$ is an electron-deficient molecule with $6$ valence electrons around $B$. $ZnCl_2$ is a covalent compound where $Zn$ does not complete its octet. $NO_2$ is an odd-electron molecule with $7$ valence electrons on the nitrogen atom. $SnCl_4$ has a central $Sn$ atom bonded to $4$ $Cl$ atoms,resulting in $8$ electrons in the valence shell of $Sn$,thus following the octet rule.

Which of the following molecules follows the octet rule?
