Chat with our AI personalities
PH3 has 3 bonding pairs and 1 non-bonding pair of electrons. Its electron pair geometry is Tetrahedral and its molecular geometry is Trigonal Pyramidal.
In having three hydrogens attached to a phosphorous atom the arrangement is forced as the lone pairs must be kept as far from each other as possible, thus the geometry here.
The molecular geometry is octahedral.
