There are 5 outermost electrons in both phosphorus and nitrogen atoms but in nitrogen no more than three unpaired electrons are possible due to absence of d-orbitals in 2nd energy level so nitrogen may form only three covalent bonds (as NCl3 and NF3) but d-orbitals are present in 3rd energy level of Phosphorus so in excited state it may have five unpaired electrons and may form PCl5.
PF5 is known because phosphorus readily forms a stable compound due to the presence of empty d orbitals which can accommodate additional electrons. In contrast, NCl5 and NF5 are not known due to the high electronegativity of nitrogen and the resultant instability of compounds with high coordination numbers. Additionally, the large size of chlorine atoms makes it difficult for them to bond with multiple nitrogen atoms.
The chemical formula for phosphorus pentafluoride is PF5.
Yes, PF5 is a Lewis acid because it can accept an electron pair to form a new chemical bond. In this case, the phosphorus atom in PF5 can accept an electron pair from a Lewis base.
PF5 :SP3d
In PF3, the central phosphorus atom uses sp3 hybrid orbitals. In PF5, the central phosphorus atom uses sp3d hybrid orbitals.
The geometry is different and also reactivity. 2F more than on PF3 trigonal bipyramidal PF5 trigonal pyramidal PF3
PF5 :SP3d
The electron geometry (and also, the molecular geometry) of PF5 is Trigonal Bipyramidal.
In PF3, the central phosphorus atom uses sp3 hybrid orbitals. In PF5, the central phosphorus atom uses sp3d hybrid orbitals.
Yes, PF5 is a Lewis acid because it can accept an electron pair to form a new chemical bond. In this case, the phosphorus atom in PF5 can accept an electron pair from a Lewis base.
It is Phosphorous pentafluoride.
No, AsH3 does not follow the octet rule. Arsenic, the central atom in AsH3, can expand its valence shell to hold more than eight electrons in bonding.
