Choose the incorrect statement about ionic/electrostatic bonds.

Strength of interaction is proportional to distance

They are the strongest intermolecular bond

They are the most important initial interaction

Choose the incorrect statement about hydrogen bonds.

An interaction of orbitals takes place

Optimally, Donor-H bond points directly at the lone pair of electrons

On benzene rings there is reduced electron density on the face, and greater electron density on the edge

It involves aromatic interactions, also alkenes

Purine / pyrimidine bases pi stack in DNA, causing it's helical shape
