Do you mean BiCl3? Boron/iodine (BI) and bismuth (Bi) can make a big difference. Because boron has 3 valence electrons, it can only bond directly with three other elements. Iodine and chlorine both have 7 valence electrons, and once they have already bonded with something, there is no free space left. Thus, BICl3 is not a molecule. If you meant for the "BI" to represent bismuth, which has 5 valence electrons (still three free sides), it can still be bonded with the three chlorines since there is no longer any iodine. Capitalization matters, so do be careful. If you meant BiCl3, then it would be polar covalent. The chlorine is shared unequally by the bismuth because the electronegativity of chlorine is much higher than that of bismuth. The pull of the chlorine is described best as the following: (NOTE: The underscores are used to prevent shifting.)
Cl<-Bi->Cl
___ |
___ v
___Cl
Because the left/right pull will cancel each other out, the downward pull would cause the molecule to be polar. I hope this helps :)
Boron trichloride (BICl3) is a polar molecule. This is because the chlorine atoms are more electronegative than boron, leading to an uneven distribution of electron density with a net dipole moment.
It is non polar
It's non polar covalent
Toothpaste is typically a mixture of polar and non-polar substances. The surfactants in toothpaste are usually polar, while other ingredients such as thickeners and abrasives can be non-polar.
It is a non polar molecule. It has optical characteristics but no charge.
Polar
Br2 (Bromine gas) is a nonpolar molecule because the two bromine atoms have the same electronegativity, resulting in a balanced distribution of electrons and no net dipole moment.
C10H8 (naphthalene) is nonpolar because it consists of only carbon and hydrogen atoms, which have similar electronegativities. As a result, the molecule does not have any significant dipole moment and is considered nonpolar.
I2 is non-polar
Oil is nonpolar because it consists of long hydrocarbon chains that do not have any significant charged regions. This means oil is overall neutral and does not interact strongly with polar substances like water.
non-polar
Water (aquades) is a polar molecule due to its uneven distribution of electrons between oxygen and hydrogen atoms, resulting in a partial positive charge on hydrogen and a partial negative charge on oxygen. This polarity allows water molecules to form hydrogen bonds with each other, leading to its unique properties such as high surface tension, cohesion, and adhesion.
KrF4 is a nonpolar molecule because the four fluorine atoms around the central krypton atom cancel out each other's dipole moment due to their symmetric arrangement.
It is non polar.
Polar contains polar. Non-polar contains nothing.
water is polar and immiscible with the non-polar octanol.
Nonpolar
ClO4 is polar.
