Question
Chapter 25, Problem 25.5YT
Interpretation Introduction
Interpretation:
Curved arrow notation in the structure to be drawn.
Concept introduction:
The additional stabilization of the allyl and benzyl radicals is also due to resonance. Even though the curved arrow notation is different from that used to indicate resonance in the cations, the unpaired electron in each radical is shared among the same carbon atoms as the positive charge is in the analogous carbocations.
