A molecule's polarity has two main contributing factors: symmetry and bond polarity. In order for a molcule to have poles, it must be asymmetrical and contain polar bonds. In the case of HI, the molecule is asymmetrical, however the difference in the electronegativities between hydrogen (with an electronegativity of 2.1) and iodine (with an electronegativity of 2.5) is technically too small for the H---I bond to be polar. However, there is a characteristic associated with polar molecules called its "dipole moment." The value of a polar molecule's dipole moment can be calculated by multiplying the bond length of the molecule (from nucleus to nucleus) by the charge of the molecules. Since iodine has such a large atomic radius, and therefore a larger bond radius than the hydrogen halides HF, HCl, and HBr, it can be thought of as having a very slight dipole moment. Therefore, HI is a polar molecule.
It's a difficult answer because one would think that it is polar because it is asymmetrical, and it's only dipole doesn't cancel out. But, the difference in electronegativity is only .4, which is classified as nonpolar. (0-.4 is nonpola4, .5-2 is polar, 2< is ionic)
Yes. HI is polar molecule.
Yes. The negative end will be iodine.
HYdrogen iodide is a dipole.

A polar molecule
When a molecule is nonpolar it means there are no charges.
Yes
Water has a polar molecule, while oil has a non-polar molecule. Because of this, oil and water are immiscible.
A polar molecule in which there is some separation of charge in the chemical bonds, so that one part of the molecule has a slight positive charge and the other a slight negative charge. A common example of polar molecule is water. The water acts as a solvent for polar molecules. A non-polar molecule has no separation of charge, so no positive or negative poles are formed.
The hydrogen iodide is an acid with polar covalent bond.

No a molecule is a molecule, polar or nonpolar.
A polar molecule.
It is a polar molecule and has polar bonds.
pure covalent/ polar covalent
a non polar molecule
water is a polar, covalent molecule. it doesn't have an unsharing molecule. its also has to do with the 8 properties of water.
O2 is non polar molecule .
Water is a polar molecule.
