Gce Model Questions Vol1 2020 Chemistry Question 22
Practice objective / multiple choice question 22 from the 2020 Gce Model Questions Vol1 Chemistry examination.
Two isomers of \(\mathrm{C_{4}H_{8}}\), namely 1‑butene (\(\mathrm{CH_{2}=CH‑CH_{2}‑CH_{3}}\)) and cyclobutane (a four‑membered ring of \(\mathrm{CH_{2}}\) groups), are combusted completely in oxygen according to the reaction \(\mathrm{C_{4}H_{8} + 6\,O_{2} \rightarrow 4\,CO_{2} + 4\,H_{2}O}\). Using the following average bond enthalpies (kJ·mol⁻¹): C-C 347, C=C 614, C-H 413, O=O 498, C=O 799, O-H 463, determine which isomer releases the greater amount of heat per gram of fuel.
