Vedclass · Answer

(B) The number of lone pairs on the central atom can be calculated using the formula: $	ext{Lone pairs} = \frac{1}{2} [V - B]$,where $V$ is the number of valence electrons of the central atom and $B$ is the number of bonding electrons (or bonds formed). For $SF_6$: The central atom Sulfur $(S)$ has $6$ valence electrons and forms $6$ bonds with Fluorine atoms. $	ext{Lone pairs} = \frac{1}{2} [6 - 6] = 0$. For $SO_2$: Sulfur has $6$ valence electrons,forms $4$ bonds with Oxygen,leaving $1$ lone pair. For $NH_3$: Nitrogen has $5$ valence electrons,forms $3$ bonds with Hydrogen,leaving $1$ lone pair. For $SF_4$: Sulfur has $6$ valence electrons,forms $4$ bonds with Fluorine,leaving $1$ lone pair. Thus,$SF_6$ has no lone pair on the central atom.
