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.
Trigonal Pyramidal
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.
1000 times more dilute
P + Na(OH) + H20 = NaH2PO2 + PH3
As you have it written NH3 donates a proton to the solution and this hydrogen ion is picked up by PH3 to make PH4; so NH3 is the acid here. ( though this reaction seems odd to me )
Trigonal Pyramidal
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.
Phosphine, or PH3, has (quite obviously) three hydrogen atoms singly bonded to a phosphorus atom. Because of the presence of a lone pair of electrons, the phosphorus atom is sp3 hybridized, and the electron orbitals adopt a tetrahedral configuration. As mentioned earlier, one orbital is non-bonding and thus the molecular shape is trigonal pyramidal.
Yes
The molecular shape of HCOOH is trigonal planar, I believe...
The shape is trigonal pyramidal Polarity is non-polar
A PH3 molecule has a triangular pyramidal shape. The central atom is the Phosphorus atom, which is connected to three Hydrogen atoms.
Molecular
PH3 forms a trigonal pyramid ClO4- forms a perfectly regular trigonal pyramid, known as a tetrahedron BeCl2 ~APEX
You might think trigonal planar, but it's actually trigonal pyramidal. Remember that phosphorus (like nitrogen) ends up with a lone pair when it bonds to three things covalently. That lone pair causes a lot of distortion and you end up with the pyramid shape.
its a trigonal pyramid but it can also be tetrahedral because it has a lone pair of electron bonded to the centrel atom (P)
Yes. PH3 is a trigonal pyramidalk structure like ammonia with a lone pair. There is an electronegtaivity difference between P and H and the bond dipoles and the lone pair contribution all give a smallish dipole moent,
