MCQ
Among the compounds, $B{F_3},NC{l_3},{H_2}S,S{F_4}$ and $BeC{l_2}$, identify the ones in which the central atom has the same type of hybridisation
  • A
    $B{F_3}$ and $NC{l_3}$
  • B
    ${H_2}S$ and $BeC{l_2}$
  • C
    $B{F_3},NC{l_3}$ and ${H_2}S$
  • ✓
    $NC{l_3}$ and ${H_2}S$
✓

Answer

Correct option: D.
$NC{l_3}$ and ${H_2}S$
(d) In $NC{l_3}$ and ${H_2}S$ the central atom of both $(N\, and\, S)$ are in $s{p^3}$ hybridization state     

while in $B{F_3}$ and $NC{l_3}$ central atoms are in $s{p^2}$ and $s{p^3}$hybridization respectively.

In ${H_2}S$ and $BeC{l_2}$ central atom are in $s{p^3}$ and $s{p^2}$ hybridization In $B{F_3},\,NC{l_3}$ & ${H_2}S$ central atom are in $s{p^2}$, $s{p^3}$ & $s{p^3}$ hybridization and in the central atom are in $s{p^3}$ and $sp$hybridization.
