Benzyl radicals are more resonance-stabilized than allyl radicals are.

Benzyl radicals are less resonance-stabilized than allyl radicals are.

In benzyl radicals, the whole aromatic system plays a part in resonance stabilization.

Benzylic bromination, which occurs without any illumination or continuous cooling and, possibly, with the help of a radical former, such as NBS, is typical of a radical mechanism.

Benzylic bromination, which occurs under illumination and boiling heat with the possible aid of a radical former, such as NBS, represents a radical mechanism.

The bromination of the aromatic nucleus follows an ionic mechanism.

The bromination of the aromatic nucleus, which requires no boiling heat, but a lewis acid catalyst instead, follows an ionic mechanism.

The bromination of the aromatic nucleus, which requires boiling heat and a lewis acid catalyst, is classified as an anionic mechanism.
