    Stuck on this question... Any help would be appreciated! (im not really sure where to start) thanks

    Rank the following substituents for their ability to stabilise an adjacent
    carbocation:
    -CH3, -CH=CH2, -CF3, -NH2, -OH.
    In each case, say which orbital interactions are involved, give an orbital energy
    diagram, and explain your ranking in terms of the relative energies of the orbitals.

    There are two ways to stabilise a positive ion:

    1. Donate it electrons via a pi orbital (+M)
    2. Induce electron density towards it along a sigma bond. (+I)
