Problem

Consider the following four bonds: I. C≡N bond in hydrogen cyanide (HCN) II. C=C bond in ethene (CH2=CH2) III. C–H bond to an sp-hybridized carbon in acetylene (HC≡CH) IV. C–C single bond in ethane (CH3–CH3) Which sequence correctly orders these bonds from greatest to least bond energy? a)

\text{I} > \text{III} > \text{II} > \text{IV}

\text{II} > \text{I} > \text{III} > \text{IV}

\text{I} > \text{II} > \text{III} > \text{IV}

\text{I} > \text{II} > \text{IV} > \text{III}
