Iodination of propane
WebFor example, propane has eight hydrogens, six of them being structurally equivalent primary, and the other two being secondary. If all these hydrogen atoms were equally reactive, halogenation should give a 3:1 ratio of 1-halopropane to 2-halopropane mono-halogenated products, reflecting the primary/secondary numbers.

WebAlex and Hannah were asked to investigate the kinetics involved in the iodination of propanone. They were given the following equation by their teacher. … WebThe professor often provides a few examples after explaining, but they aren’t enough to be sure of a pattern. If enough examples are provided for each concept, I imagine it would be relatively easy to pick up the rules. It would also feel like solving an engaging puzzle instead of just being told a bunch of rules. 7 comments.
WebThe reaction between propanone and iodine is first order with respect to propanone and first order with respect to the hydrogen ions which catalyse the reaction. The order with respect to iodine can be determined by taking a reaction mixture in which the initial concentrations of propanone and hydrogen ions are very much larger than that of iodine.
