Carbocations!

One of my favorite questions was back when we were learning about Carbocations. In the book, there were a lot of problems that referenced the stability of them. Here is one of my favorite questions was Chapter 6, the end of section 6.2, practice problem #4.

4. List the following carbocations in each set in order from most stable to least stable:
                       CH3                                         +                                                              +
A. CH3-CH2-C-CH3                   CH3-CH2-CH-CH3                       CH3-CH2-CH2-CH2
                       +


Solving A, Tertiary is most stable, then followed by secondary and primary.

                          +                                                +                                                +
B. CH3CHCH2CH2                      CH3CHCH2CH2                      CH3CHCH2CH2  
             F                                                 CL                                            CH3


Solving B, Since they are all primary Carbocations we must look at the electronegativity and place them in the proper order.
