Benzophenone is a naturally occurring organic compound with the formula (C 6 H 5) 2 CO, generally abbreviated Ph 2 CO. Benzophenone has been found in some fungi, fruits and plants, including grapes. [4] It is a white solid with a low melting point and rose-like odor [5] that is soluble in organic solvents. Benzophenone is the simplest ...
Biphenyl (also known as diphenyl, phenylbenzene, 1,1′-biphenyl, lemonene [4] or BP) is an organic compound that forms colorless crystals. Particularly in older literature, compounds containing the functional group consisting of biphenyl less one hydrogen (the site at which it is attached) may use the prefixes xenyl or diphenylyl .
Diphenylmethanol is the organic compound with the formula (C 6 H 5) 2 CHOH. Also known as benzhydrol , it is a white solid and the parent member of a large class of diaryl alcohols. Preparation
Many ketones contain the benzoyl group. They have the formula C 6 H 5 CO–R, an important example being benzophenone. Benzoyl esters and amides are common in organic chemistry. The esters are used as a protecting groups in organic synthesis, [4] which can be easily removed by hydrolysis in dilute basic solution.
[1] [2] [3] Most are based on two hydroxyphenyl functional groups linked by a methylene bridge. Exceptions include bisphenol S, P, and M. "Bisphenol" is a common name ; the letter following denotes the variant, which depends on the additional substituents.
It is generally considered an inductively withdrawing group (-I), because of the higher electronegativity of sp 2 carbon atoms, and a resonance donating group (+M), due to the ability of its π system to donate electron density when conjugation is possible. [5] The phenyl group is hydrophobic. Phenyl groups tend to resist oxidation and reduction.
