Question

What may be the geometry of molecule if $A{X}_3$ molecule has non - zero dipole moment?

• A. Trigonal planar
• B. Bent T - shape
• C. Pyramidal
• D. Both (b) and (c)

Answer 1

The correct option is D Both (b) and (c)

For a central atom with 3 ligands, it is already given
that the dipole moment is non-zero. This means that the molecule's
structure is non-symmetrical. We are left with pyramidal and T-shaped.
We can make a case for both such cases!
