PH3, AsH3, SbH3 Intermolecular forces
My book keeps referring to how the group 5 hydrides have only VDW forces, with no permanent dipole-dipole interactions.
Surely this is incorrect; the lone pair on each of these molecules results in a trigonal pyramidal shape, and thus a polar molecule?
Hence the group 5 hydrides should have permanent dipole-dipole interactions?
