Trityl methane
WebTriphenylmethane, or triphenyl methane, is a hydrocarbon. It is a colorless to light brown powder. ... Triphenylmethane is significantly more acidic than most other hydrocarbons because the planar trityl anion is stabilized by extensive delocalization over three phenyl rings. The trityl anion absorbs strongly in the visible region, making it ...
