∙ 11y agoSymmetrical molecules(SYMMETRY). Because of symmetry molecules that have polar bonds are overall NONPOLAR (+ and - charges cancel or balance out).
Asymmetrical molecules (NO SYMMETRY). If a molecule has polar bonds (and there is no symmetry to cancel out + and - charges), the molecule is polar.

∙ 14y agoThe oxygen atom of a water molecule has a d- (delta negative) charge and the two hydrogens both have a d+ (delta positive) charge, a dipole exists. This allows for hydrogen bonding to occur between one or more water molecules where the d+ hydrogen atom of one water molecule is attracted to the d- charge of the oxygen on another

∙ 13y agoA symmetrical molecule can be polar, such as H2O (water). Either the charge distribution can be in another direction than the symmetry (as for water) or there can be a charge distribution which has an extreme in the center and opposite extremes at the ends.
E.g.
Water:
O-
/ \
H+ H+
So even though water is symmetrical (mirror plane through the middle, left and right are the same but inverted), it has a polarity > 0 because the top is negative and the bottom is positive.

Trigonal Planar
Tetrahydral
Trigonal Bipyramid
Octahedral
Square Planar
These are the symmetrical molecular shapes.

∙ 11y agoSymmetry and polarity are, in most senses, antonyms. If the molecule is symmetrical it is the same all around. Such a molecule would be non-polar.

Why is NBr3 a non-polar molecule?
If the difference in electronegativity is greater than 0.3 than it is Polar. Nitrogen and Bromine the difference is less than .3 so it is nonpolar
H3O plus is a polar or nonpolar molecule?
H2O is a polar molecule; +H3O is even more so.
What kind of molecule is Cl2 polar or non polar?
Halogen molecules are not polar.
A molecule having slighty negative and positive ends with regard to change?
a molecule having slightly negative and positive ends with regard to change
Why is a polar molecule?
A molecule is polar because it has an uneven distribution of electrons within it. For example the oxygen in H2O has a higher electronegativity than the hydrogen. This means that the oxygen will possess more of the electron, and therefore more of the negative charge than the hydrogen, leading to a polar molecule.
What determines if a molecule is polar or non polar?
if the molecule is symmetrical, then it is nonpolar. if it is NOT symmetrical, it is polar. Ionic bonds form between a metal and a nonmetal.
Is beryllium dichloride a polar molecule?
BeCl2 is listed as a non-polar (symmetrical) molecule
Why is H2O an example of polar molecules?
h2o is an example of a polar molecule because when you look at the molecule it is not symmetrical. therefore it is polar.
Is iodine polar or non polar?
An iodine molecule is formed by two 'I' atoms. It implies that the molecule is symmetrical and it is non-polar.
How can the shape of a molecule determine its polarty?
A symmetrical molecule cancels out the effects of polar bonds
Is carbon tetrachloride a symmetrical molecule?
The bond in carbon tetrachloride are polar covalent, but the CCl4 molecule a a whole is nonpolar due to the symmetrical arrangement oft he bonds.
How to know if a substance is a polar or not?
First of all you have to draw the Lewis dot structure of the molecule. If the molecule is symmetrical, it's non-polar. If the molecule is non-symmetrical or asymmetrical, then the molecule is polar.
How can the shape of a molecule determine it's Polarity?
A symmetrical molecule cancels out the effects of polar bonds.
Why is CH4 not a polar molecule?
It has no lone pairs.Bonds are similar and has a symmetrical shape.
What is the other factor in whether or not a molecule is polar?
a molecule is polar if it has a lone pair of electrons or if it's not symmetrical (bonded to different elements such as HCN)
Why would a molecule be non polar even if its bond are all polar?
If the structure of the molecule is compact and symmetrical there may not be any discernible polarity.
Does sugar contain polar molecules?
Yes, it does. The molecule is not symmetrical so it has polarity.
