Consider the acid-base reaction between iodoethane (CH3CH2I) and hydroxide (-OH). CH3CH2I + OH- --> CH3CH2OH + l- Use the table of bond energies to estimate the change in enthalpy (∆H in kJ/mol) for this reaction. Think about the bonds that are broken and that are formed. This reaction is endothermic, exothermic or energy neutral Using your calculation, what can you say about the strengths of the bonds? -The bonds before the reaction are stronger than the bonds after the reaction. -The bonds after the reaction are stronger than the bonds before the reaction. or -The bonds before and after the reaction are equivalent in strength.
