Allylic Radicals Bromination Mechanism

For (a) (iii), how do you get the second product listed in the answers manual? I just can't visualize it.

What about (c) (i), why are there three resonance structures? If a hydrogen is taken away from a specific carbon of the initial molecule to have a radical, there is no way you can have three resonance structures.

The barrier to rotation in the allyl radical is low (~[15-16 kcal/m](http://pubs.acs.org/doi/abs/10.1021/ja00405a032http://)) and it can undergo cis-trans isomerization.

As to question (c)(i), you're right, there are only two resonance structures.

What you show above with three resonance structures is the [trimethylenemethane diradical](http://en.wikipedia.org/wiki/Trimethylenemethane), isobutene with 2 allylic hydrogens removed.
