Webphenyl: [noun] a monovalent aryl radical C6H5− derived from benzene by removal of one hydrogen atom. WebIt is sometimes referred to as “allylic” resonance, especially in cases with all carbon, since it is patterned after the (all-carbon) allyl group. With type IV resonance of anions, the major form involves placing the negative charge on the atom that can handle the charge best, often the more electronegative oxygen or nitrogen.
