no because in order to be classified as polar you must have lone pairs. So that would be a contradiction. I assume so
SeI4 is polar.When a compound hasno lone pairs2 lone pairs and 4 atoms4 lone pairs and 2 atoms3 lone pairs and 2 atomsit is non-polar. All others are polar.
The molecular geometry of a compound helps to determine polarity because, it indicates the number of lone pairs on a central atom thus giving it specified angles and polarity (only if there are lone pairs because if there are no lone pairs on the central atom, them it is non-polar).
PBr5 is non-polar because it is a trigonal bipyramid with no unbound pairs.
The geometry of XeO3 is trigonal pyramid with an unsymmetric charge distribution. Therefore this molecule is polar. (This came from my chemistry book)
PH3 is a non-polar covalent molecule. This is somehow confusing because, when you draw out the Lewis diagram, you will observe a lone pair on the P atom. However, if the electronegativity difference does not have a polar bond, then no matter what happens, it will always be non polar. In this case, the EN is 0.01, which indicates non polar. (Non polar EN is 0~0.4)To decide whether a molecule is polar or non-polar, first draw the Lewis diagram. Then calculate the electronegativity. If the electronegativity is non polar, then no matter it has lone pairs or it has more than one group around the central atom, it will always be non polar. In this case, PH3 is non polar because of it has a non polar bond indicated by the electronegativity even though it has lone pairs.But if the bond is polar, then you might have a chance to get a polar molecule depending on either of these 2 factors:1. If there are lone pairs2. If there are other groups around the central atomFor example, H2O is polar because:1.It has a polar bond for electronegativity2.It has lone pairs(Even if it doesn't have a other groups around the central atom, it's still polar because it's polar if you just satisfy either of the 2 conditions)If both conditions of the above are not met, then it's non polar even if it has a polar bond. Like CO2, a molecule has a polar bond, but fails to meet both of the conditions, is a non polar molecule.Always remember to check your electronegativity. Remember if a molecule only has non polar bonds, then it must be a non polar molecule no matter which condition is satisfied after (ex. lone pairs). If a molecule has polar bonds, then it may be a polar molecule depending on either of the 2 conditions listed.
IO3- is a polar molecule due to its trigonal pyramidal molecular geometry and the presence of lone pairs on the central iodine atom. This asymmetry creates a net dipole moment, making the molecule polar.
No, O3 (ozone) consists of two polar covalent bonds and one non-polar covalent bond. The overall molecule is polar due to the arrangement of the bonds and the lone pairs of electrons on the central oxygen atom.
In methane (CH4), the central carbon atom does not have any lone pairs of electrons. Instead, it forms four single covalent bonds with the four hydrogen atoms around it.
It is a polar compound.
Polar compound.
It is non-polar because it is a carbonic compound.
Non polar. It is a hydrocarbon and most hydrocarbons are nonpolar.
