This question usually refers to phosphorus halides and refers to the polarity od =f individual P-X bonds- less polar means "more covalent"
Different ways of looking at this:-
higher oxidation state => higher electronegativity of central atom=> less polarity=> more covalent
higher coordination number=> more halides pulling at electrons=> they each get less=> less polarity=> more covalent
Please not that the PCl5 and PBr5 are ionic solids (PCl4+ PCl6-) (PBr4+ Br-) and are monomers in liquid and vapour.
Also note that change in coordination doesn't seem to change bond lengths- except that axial P-X bonds are longer in PX5 than equatorial.
Also note the question--how could you show whether this prediction is borne out by observation? Chemistry is an evidence based subject after all. Answer? I don't know- classic method is dipole but that is meaningless as PX5 are symmetric so no dipole observed.
What else can I help you with?
Does phosphorous pentahalides exist?
There are no such compounds existing other than phosphorous pentafluoride (PF5).
How does group 3 trihalides attain octet configuration?
Group 3 trihalides, such as aluminum trichloride (AlCl₃), achieve octet configuration through covalent bonding with halogen atoms. In these compounds, the central metal atom shares its three valence electrons with three halogen atoms, forming three covalent bonds. This sharing allows the halogens to complete their octets, while the metal atom can achieve an effective octet through this bonding, even if it initially has fewer than eight electrons. In some cases, such as with AlCl₃, the central atom can also form dimeric structures to stabilize its electron configuration.
Which is more covalent H-Cl or Cl-Cl?
H-Cl is more covalent than Cl-Cl because the difference in electronegativity between hydrogen and chlorine is greater than that between two chlorine atoms, leading to a more polarized and covalent bond between H and Cl.

Can silicon form more than 4 covalent bonds?
No, silicon can form only four covalent bonds.
Is a single covalent bond stronger than a double covalent bond?
A double covalent bond is stronger than a single covalent bond because it involves the sharing of two pairs of electrons between atoms, creating a stronger bond. In a double bond, the atoms are held together more tightly than in a single bond, making it more difficult to break.
Which bond is most common covalent or ionic?
Covalent bonds are more common than ionic bonds in nature. This is because covalent bonds involve the sharing of electrons, which is a more stable arrangement compared to the transfer of electrons seen in ionic bonds. In covalent bonds, atoms can achieve a full outer electron shell without gaining or losing electrons.
What are some covalent compounds with more than three elements?
Nucleic acids would be one example of a covalent compound with more than 3 elements. Proteins have more than 3 elements as well. Many organic compounds do, it is quite common.
Is a hydrogen bond stonger then a covalent bond?
No, a hydrogen bond is weaker than a covalent bond. A hydrogen bond is an electromagnetic attraction between polar molecules, while a covalent bond involves the sharing of electrons between atoms. Covalent bonds are typically stronger and more stable than hydrogen bonds.
Why ionic azides are more stable than covalent azides?
Ionic azides are more stable than covalent azides primarily due to the strong electrostatic interactions between the positively charged cation and the negatively charged azide ion (N₃⁻). This ionic bonding provides a more stable lattice structure, while covalent azides rely on weaker covalent bonds that can be more susceptible to decomposition. Additionally, the azide ion has a resonance stabilization that can further enhance the stability of ionic azides compared to their covalent counterparts.
Why cucl is more covalent than nacl?
cucl is more covalent than nacl because cu has same size as that of na & cucl has pseudonobal gas configration due to which it has 18 electrons in outermost shell than na cl which has 8 elctrons
Can atoms share more than 1 pair of electrons in a covalent bond?
yes
