A molecule with zero dipole moment implies that it has a symmetrical distribution of electron density and charge. MX3 indicates that the central atom M is bonded to three X atoms.
For a molecule to have a zero dipole moment, the three X atoms should be arranged symmetrically around the central atom M. This arrangement is possible in a trigonal planar geometry.
In a trigonal planar geometry, the bond angles between the X atoms are 120 degrees. This geometry can be achieved when the central atom M uses sp2 hybrid orbitals for bonding.
In sp2 hybridization, one s orbital and two p orbitals of the central atom mix to form three sp2 hybrid orbitals that are oriented at 120 degrees to each other. These hybrid orbitals can then form sigma bonds with the X atoms, resulting in a trigonal planar geometry and a molecule with zero dipole moment.
