7. Chemical reactions are often thought about as reactions between two independent molecules (intermolecular). A reaction can also happen between two different functional groups on the same molecule attached in different places (intramolecular). Intramolecular reactions typically "win out” over intermolecular reactions when the formation of a 5-membered ring or 6-membered ring is possible, as these are the most stable of all ring structures. One can determine if an intramolecular reaction will occur by counting each atom from the most negatively charged atom to the most positively charged atom. This number will equal the size ring closed during the reaction. Below the most negative atom is oxygen and most positive atom is the carbon in a polarized bond with chlorine. It is helpful to number your substrate and products similarly to help keep track of the existing bonds and new bonds. C 5 5 4 There are two intramolecular reactions that can occur under the following reaction conditions. Draw the detailed mechanism (curved arrows) that lead to each of the products (2 total mechanisms). Circle which product is most likely going to be favored due to stability. Remember that proton transfer reactions are much faster than nucleophile/electrophile reactions. Br NaOH H DMSO Br
