phenyl

(fĕn`əl), C6H5, organic free radicalfree radical,
in chemistry, a molecule or atom that contains an unpaired electron but is neither positively nor negatively charged. Free radicals are usually highly reactive and unstable. They are produced by homolytic cleavage of a covalent bond (see chemical bond); i.e.

 or alkyl groupalkyl group
, in chemistry, group of carbon and hydrogen atoms derived from an alkane molecule by removing one hydrogen atom (see radical). The name of the alkyl group is derived from the name of its alkane by replacing the -ane suffix with -yl, e.g.

In addition, the comparison made between PADA-1 and PAD suggested that PADA-1 with hydrophobic groups (phenyl group) had a higher E1 removal efficiency.
Since the DPPS has more phenyl groups at the side of Si atoms compared with PMPS and PPS, molecular interactions created by the phenyl groups would affect the nucleation and crystal growth.
The methyl groups in the ortho position to the imide ring twist the phenyl groups out of the plane, creating for each polymer four possible conformational preferences depending on the relative orientation methyl groups to the plane created by the imide rings; +, -: +,-: -,+:+:,-; -,+: +,-; (note shown), -,+:-, + (not shown).
The carboxyl group or the group of sulfonyl hydroxide can form a H-bond with key residue Arg316 in the docking pose, and the phenyl group next to the carboxyl group or the group of sulfonyl hydroxide can form a [pi] interaction with residue Phe313.
The cis-deprotonation mechanism of the cis-Pd[([PPh.sub.3]).sub.2](Ph)Br complex (Scheme 2, II) starts with the dissociation of the triphenylphosphane ligand in the cis-position to the phenyl group from complex 10 and the formation of the cis-Pd([PPh.sub.3])(Ph)Br complex (Scheme 2, 19).
This may be accounted for on the basis of a steric interaction effect caused by the bulky butyl groups in the case of dibutyltin(IV) and phenyl groups in the case of diphenyltin(IV).
Prior to this study, dihdroisoxazoles of this substitution type [methyl and substituted phenyl group at the 5 position] have been difficult to prepare by other methods.
The incorporation of a phenyl group in the backbone of the polymer gives the stationary phase greater thermal stability, which reduces column bleed.
They substitute small bridging structures (rectangles in right diagram) made from an organic chemical -- such as acetylene (C:C) or a phenyl group ([C.sub.6.H.sub.4]) -- for some oxygen atoms.
The methyl-pyrazolone-hydrazine cores are essentially planar with RMS deviation of fitted atoms of 0.0281 for Empp-Ph, 0.0285 for Prmpp-Ph, and 0.0493 for PmppPh indicating that the phenyl group in Pmpp-Ph exhibits greater steric hindrance [25].
From the simulation, it can be found that the inhibition efficiency afforded by DEAMB may be due to the its electron rich N atoms, imidazole and phenyl group, and the possible coordination points are unshared electron pair of heteroatoms and p-electrons of imidazole and phenyl group.
Represented by the chemical formula C6H5OH, phenol is similar to alcohols as the phenyl group (C6H5) in it is bonded to a hydroxyl group (OH).
