3Choose the incorrect statement about ionic/electrostatic bonds.
- AThey are the strongest intermolecular bond
- BStrength of interaction is proportional to distance
- CThey are the most important initial interaction
4Choose the incorrect statement about hydrogen bonds.
- AAn interaction of orbitals takes place
