Which type of bond exemplifies a weak chemical bond? covalent bonds in solution hydrogen bonds in solution ionic bonds in solids
vova2212 [387]

Covalent bonds in solution, hydrogen bonds in solution, ionic bonds in solids, nonpolar covalent bonds in solids- the weakest bond is hydrogen bond.

What is a chemical bond?

A chemical bond is a strong bond that can be formed between atoms, ions, or molecules to create chemical compounds. In covalent bonds, the electrons are shared, whereas in ionic bonds, the electrostatic attraction of two ions with opposing charges forms the link. Strong bonds, also known as primary bonds, include covalent, ionic, and metallic ties. Weak bonds, also known as secondary bonds, include dipole-dipole interactions, the London dispersion force, and hydrogen bonds.

Since there is no necessity for an electron exchange during formation, the hydrogen bond is weak. As a result, it is simpler to break apart a hydrogen connection between two molecules.
