Hydrogenation of double and triple bonds is an important industrial process. Calculate (in kJ) the standard enthalpy change ΔH° for the hydrogenation of ethyne (acetylene) to ethane using average bond enthalpies (use exam data sheet values).
H–C≡C–H(g) + 2H2(g) → H3C–CH3(g)
Given that ∆H° for the reaction is -42 kcal/mol and the bond dissociation enthalpies for the C - H, C - Cl, and O - H bonds are 101, 85, and 105 kcal/mol respectively, calculate the bond dissociation enthalpy of the O - Cl bond.
