Methane

Vedclass · Answer

(A) is the correct answer.$1$. In $CH_{4}$ (Methane),the central carbon atom forms $4$ covalent bonds,sharing $8$ electrons in its valence shell,thus completing its octet.$2$. In $SF_{6}$ (Sulphur hexafluoride),the central sulphur atom has $12$ electrons,which is an expanded octet.$3$. In $AlCl_{3}$ (Aluminium chloride) and $BF_{3}$ (Boron trifluoride),the central atoms ($Al$ and $B$) have only $6$ electrons in their valence shells,representing an incomplete octet.

Label	Order	Property
$i.$	$NH_3 > H_2O > SO_2$	Bond angle
