The carbocation intermediate has to be drawn and resonance structure has to be drawn for the carbocation. Concept Introduction: Unimolecular nucleophilic substitution reaction ( S N 1 ) : Reaction of alkyl halide with nucleophile involves two step processes, Loss of leaving group, where the loss of leaving group from the substrate gives a carbocation intermediate. Nucleophilic attack: A nucleophile attacks the carbocation intermediate to afford the product. Leaving group: It is a fragment that leaves substrate with a pair of electrons via heterolytic bond cleavage. Nucleophile: Donates pair of electrons to positively charged substrate resulting in the formation of chemical bond . Resonance is an electron displacement effect for stabilizing a molecule through delocalization of bonding electrons in the pi orbital. Delocalized electrons stabilize a compound. The extra stability gains from having delocalized electrons are called resonance stabilization or resonance energy.

For each scenario below, select the color of the solution using the indicator thymol blue during the titration. When you first add indicator to your Na2CO3solution, the solution is basic (pH ~10), and the color is ["", "", "", "", ""] . At the equivalence point for the titration, the moles of added HCl are equal to the moles of Na2CO3. One drop (or less!) past this is called the endpoint. The added HCl begins to titrate the thymol blue indicator itself. At the endpoint, the indicator color is ["", "", "", "", ""] . When you weren't paying attention and added too much HCl (~12 mL extra), the color is ["", "", "", "", ""] . When you really weren't paying attention and reached the second equivalence point of Na2CO3, the color is
