For 10 points, identify this aryl group that is a benzene lacking a hydrogen, giving it formula C6H5 and often abbreviated Ph.
In the Fischer indole synthesis, a hydrazine with this moiety in place of one of the hydrogens is reacted with an aldehyde or ketone. A byproduct of the Wittig reaction is a compound with three of these moieties. Two of these moieties bound together are the basis for PCBs. This compound is bound to ethene in styrene, the monomer of polystyrene. A mutation in the enzyme that hydroxylates the amino acid with this cyclic group bound to another amino acid, to tyrosine is the cause of PKU. That amino acid consists of this moiety attached to an alanine instead of its normal methyl group.

phenyl (FEE-nil) group [or Ph until it is read; do not accept \"phenol\" (fee-GNOLL) - if in doubt, have the player spell it]
