Its all down to shape and electronegativity of P and I. P and I have slightly different electronegativities so the P-I bonds would be predicted to be just polar. The shape is predicted by VSEPR theory to be determined by the number of electron pairs around the P atom. In PI3 there are four, three forming the bonds and one lone pair-- - so PI3 is a trigonal pyramid - (electron pairs are roughly tetrahedrally placed and one of them is the lone pair). the molecular symmetry means that any dipole in the bonds is not cancelled out- so expect a very small dipole moment. This is what is found.
What else can I help you with?
Which statement best describes the polarity of the molecule PI3?
PI3 is a polar molecule due to the uneven distribution of electron density caused by the lone pairs on the central phosphorus atom and the three iodine atoms. This results in a net dipole moment for the molecule, making it polar.
Is the molecule co polar or nonpolar?
The molecule is nonpolar.
Are polar solutes soluble in nonpolar solvents?
No, polar solutes are generally not soluble in nonpolar solvents.
Is artificial flavor polar or nonpolar?
Artificial flavors can be either polar or nonpolar, depending on their chemical structure. Some artificial flavors may have polar functional groups (such as hydroxyl or carbonyl groups), making them polar molecules, while others may have nonpolar structures, making them nonpolar molecules.
How polar and non polar bonds affect solubility?
Molecules with many polar bonds are soluble in polar solvents.Also, molecules with none or few polar bonds (many non-polar bonds) are soluble in non-polar solvent. e.g Water is a polar solvent so substances with many polar bonds are soluble in it.

Is HBr polar or nonpolar?
Polar
Is PF3Cl2 polar or nonpolar?
polar
Is peanut butter polar or nonpolar?
nonpolar. The fat molecules in peanut butter are nonpolar, that is why peanut butter doesn't evenly mix with water, a polar substance.
How do you explain the phrase like dissolves like in terms of polar and nonpolar substances?
Polar substances dissolve other polar substances, and nonpolar substances dissolve other nonpolar substances. A polar substance cannot dissolve a polar substance and a nonpolar substance cannot dissolve a polar substance.
Is HAsCl4 polar or nonpolar?
The shape is trigonal bipyramidal and all the atoms on the outside are the same so the charges cancel eachother. Nonpolar
