2. A student working in a perfumery lab was investigating the properties of a molecule they referred to as "Flavorol". Skillfully, they executed the synthesis of the compound by an SN2 reaction on an alkyl chloride, and it was a glorious day at work! Unfortunately, the vial used to store their product sample was found to be contaminated with a small, catalytic amount of sulfuric acid, which turned their product into something else overnight. What could have formed in the vial? CI KOH "Flavor-ol" OH "oops"

Following is an equation for iodination of toluene. This reaction does not take place. All that happens under experimental conditions for the formation of radicals is initiation to form iodine radicals, I , followed by termination to reform I2. How do you account for these observations?
The following figure shows the energy profile of a nucleophilic substitution reaction. Potential energy :ÖH H HII.C H C-1 H HO--C---I HH Reaction coordinate H -CH HO–CHITH H + 1 According to this, it is correct to affirm: O The activation energy (4G°) shows that it is thermodynamically favorable. O Represents a reaction that occurs in one step where a pentavalent chemical species is formed. O The intermediate has lower energy than any transition state. O The formation of the intermediate releases energy and is therefore thermodynamically favourable.
