Question

which of the following is a bond between two molecules?
a chemical bond in which no electrons are shared
a chemical bond in which electrons are shared with another molecule
a chemical bond in which a positively charged ion attracts a negatively charged ion
a chemical bond in which electrons are shared between atoms

Explanation:

A bond between two molecules can be an intermolecular force. An ionic bond (where a positively - charged ion attracts a negatively - charged ion) can act between two ionic compounds (which are made of molecules in a sense). Covalent bonds (electrons shared between atoms) and bonds with no electron - sharing are intramolecular. Sharing electrons with another molecule is not a standard bond description. Ionic bonds can act between molecules of ionic substances.

Answer:

a chemical bond in which a positively charged ion attracts a negatively charged ion
