Phenylphosphine is an organophosphorus compound with the chemical formula C6H5PH2. It is the phosphorus analog of aniline. Like other primary phosphines, phenylphosphine has an intense penetrating odor and is highly oxidizable. It is mainly used as a precursor to other organophosphorus compounds. It can function as a ligand in coordination chemistry.

WebResonating structures can be visualised by drawing a Lewis structure; however, it is important to note that these structures cannot be observed in nature. The molecule doesn’t go back and forth between these configurations; rather, it is an intermediate structure with overall lower energy than each of the possible configurations. Web× Close.
