Question

If molecule mx3 has zero dipole moment the sigma bonding orbital used bym are

Answer 1

Explanation:

Since, the molecule MX3 has zero dipole moment, the σ - bonding orbitals used by M (atomic number 21) are sp2-hybridized.In this case plane triangular geometry results in the cancellation of the dipole moments of individual M−X bonds. Hence, the overall molecule has zero dipole moment.
