Although neopentylbromide is a primary alkyl halide, it presents a lot of steric hindrance close to the leaving group, which slows the SN2 process significantly. There is no such hindrance in methylbromide.
Add the curved arrows to complete each transformation below (extra intermediates may need to be drawn). SOLUTION
List the following carbocations in decreasing order of their stability. SOLUTION
