Draw another resonance form for each of the substituted allylic cations shown in the preceding figure, showing how the positive charge is shared by another carbon atom. In each case, state whether your second resonance form is a more important or less important resonance contributor than the first structure. (Which structure places the positive charge on the moresubstituted carbon atom?)
Solution 4P
Both the resonance forms are allylic carbocations. The first and the second resonance forms are...
