- Decide which compounds from the list below are best suited for nucleophilic addition reactions and which ones are more appropriate for nucleophilic substitution reactions.Write TRUE if the statement is correct and FALSE if the statement is wrong. Please answer them all Substitution reactions do not occur in aromatic rings because of pi-electron delocalization. The resulting iodinated aspirin has a higher Rf compared to aspirin after visualizing with ferric chloride. The mobile phase used in determining the Rf of the iodinated aspirin is 5% ethyl acetate in acetic acid. When isopropyl alcohol reacts with HCI, the resulting product is 2-chloropropane. In Fehling's test, the theoretical product after an aldehyde is mixed with Fehling's Solution is alcohol. lodoform, which has a molecular formula of CH3l, is indicative that a ketomethyl group is present. Based on the physical property, hydroquinone has a lower boiling point compared to catechol. Picric acid, being a phenolic compound, tests positive for the FeCl3 test.
