Gce Model Questions Vol1 2021 Chemistry Question 8
Practice objective / multiple choice question 8 from the 2021 Gce Model Questions Vol1 Chemistry examination.
When the alkene \(\mathrm{C_5H_{10}}\) is hydrogenated with \(\mathrm{H_2}\) to give the alkane \(\mathrm{C_5H_{12}}\), the enthalpy change is \(-120\ \text{kJ mol}^{-1}\). Using the average bond enthalpies \(E_{\mathrm{C=C}} = X\ \text{kJ mol}^{-1}\) (unknown), \(E_{\mathrm{C-C}} = 347\ \text{kJ mol}^{-1}\), \(E_{\mathrm{C-H}} = 413\ \text{kJ mol}^{-1}\) and \(E_{\mathrm{H-H}} = 436\ \text{kJ mol}^{-1}\), calculate the experimental bond enthalpy of the C=C bond in this alkene.
