How do you determine the chemical reactivity of a compound? Provide an example.

(N/A) The chemical reactivity of a compound is inversely related to the bond enthalpy required to break its bonds. As the energy required to break the bond decreases,the chemical reactivity of the compound increases.
For example,alkenes contain a $\pi$-bond,which has a lower bond enthalpy compared to the $\sigma$-bonds found in alkanes. Consequently,alkenes are more chemically reactive than alkanes.
