How do molecules interact with each other?
The hydrogen involved in the hydrogen bond and the electronegative atom to which it is covalently bound are together known as the hydrogen bond donor. The electronegative atom that bears the lone pair is known as the hydrogen bond acceptor. Molecules can also interact with each other through atoms in nonpolar bonds.
What are intermolecular interactions?
As we shall see, intermolecular interactions occur between fully charged, partially charged, and transiently charged atoms. Ionic interactions are attractive interactions that occur between oppositely charged ions, that is, atoms that carry a charge that is at least equal to the full charge of a proton or electron.
Which molecule has the strongest intermolecular interactions?
The strength of such interactions increases with charge. Ions have the most charge, and as a result, the interactions that form between oppositely charged ions are the strongest intermolecular interactions. Next strongest are interactions between molecules that contain polar bonds.
What are the hydrogen bond interactions of onlymolecules?
c) Onlymolecules with hydrogen bound to ?uorine, nitrogen or oxygen have hydrogen bond interactions, which increase according to the num- ber of possible hydrogen bonds that may exist and the electronegativi- ties of ?uorine, oxygen and nitrogen.
