Final answer:
b. A hydrogen bond exemplifies a weak chemical bond, forming between a hydrogen atom and a strongly electronegative atom.
Step-by-step explanation:
The type of bond that exemplifies a weak chemical bond is b. Hydrogen bond.
A hydrogen bond is a weak bond formed between a hydrogen atom and a strongly electronegative atom, such as fluorine, oxygen, or nitrogen. The hydrogen atom is partially positive and is attracted to the partially negative atom, creating a relatively weak bond.
