WebThe primary quantum yield for the photo-dissociation of iodine in degassed hexane at 25° has been calculated from measurements of the mean lifetime of the chains involved in the exchange of iodine atoms with trans-diiodoethylene. The primary quantum yield to an accuracy of ±15 percent is 0.59 at 436 mμ and 0.37 at 578 mμ. The deviation of this … WebFREE SOLUTION: Q. 9.85 Why does iodine dissolve in hexane, ... Iodine should dissolve the most in nonpolar solvents because it is a nonpolar chemical. Iodine is best dissolved in diethyl ether. Step 3: Explanation. Since iodine is a non-polar ion, it will melt in a non-polar solvent like hexane.
