MCQ
If a molecule $M{X_3}$ has zero dipole moment, the sigma bonding orbital used by M are
  • A
    $s{p^3}d - $hybrid
  • B
    $sp - $hybrid
  • C
    $s{p^3}{d^2} - $hybrid
  • ✓
    $s{p^2} - $hybrid
✓

Answer

Correct option: D.
$s{p^2} - $hybrid
(d) $M{X_3}$ show the $s{p^2}$ hybridization in which $3s{p^2}$hybridized orbital of $M$ bonded by $3X$ from $\sigma $ bond and having the zero dipole moment.
