Question

If a molecule MX3 has zero dipole moment, the sigma bonding orbital used by M are (A) sp3 d-hybrid (B) sp-hybrid (C) sp3 d2-hybrid (D) sp3 -hybrid

If a molecule MX3 ( e.g., BF3) has a zero dipole moment, the σ-bonding orbital used by M are sp2-hybrid. The zero dipole moment is due to its symmetrical (trigonal planar) structure.

Q. If a molecule $M X_{3}$ has zero dipole moment, the sigma bonding orbital used by M are

$s p^{3} d - h y b r i d$

sp-hybrid

$s p^{3} d^{2} - h y b r i d$

$s p^{3} - h y b r i d$

$s p^{2} - h y b r i d$

If a molecule $M X_{3}$ ( e.g., $B F_{3}$ ) has a zero dipole moment, the $σ$ -bonding orbital used by M are $s p^{2}$ -hybrid. The zero dipole moment is due to its symmetrical (trigonal planar) structure.
