How to tell which is most polar?
To determine which molecule is the most polar, compare the electronegativity difference between the atoms in each molecule. The greater the electronegativity difference, the more polar the molecule. Additionally, look at the molecular geometry and symmetry of the molecule, as asymmetrical molecules tend to be more polar.
Molecules that have an unequal distribution of charges?
A molecule with an uneven distribution of charge is said to be a polar molecule. A polar molecule, because of an uneven distribution of charge, basically has an "end" that is slightly more positive and another that is slightly more negative. Let's look at an example.The water molecule is a good example of a polar molecule. It's oxygen end is a bit more negative, and the end with the pair of hydrogen atoms on it is slightly more positive. That gives the molecule an overall "endedness" with a positive and a negative end.
Identify the molecule that has polar bonds but is non-polar out of BCl3 NH3 SCl2 CHCl3 and H2S?
You need to look at the molecular geometry using VSEPR theory in order to answer this question. If you do so, you'll find that one of the molecules is both planar and symmetric within that plane. That's the non-polar compound. (In other words: I've given you a hint; do your own homework.) the hint is about BCl3 but it has a net dipole so it is also polar.
Is h2f polar or nonpolar?
Any bond is polar only when there is a net dipole moment of the molecule. Polar bonds occur only when among the bonding atoms, one atom is more electronegative than the other one. But in case of H2 molecule both are hydrogen atoms and have same electronegativites. Thus, their bond is non- polar.
What is the difference between polar and non polar?
The difference between a polar and non-polar molecule is in terms of sharing electrons. In the case of a polar molecule, electrons are not shared in an equal manner among the atoms that made the bond. But in the case of a non-polar molecule, electrons are shared in an equal manner among the atoms that made the bond.
How to tell which is most polar?
To determine which molecule is the most polar, compare the electronegativity difference between the atoms in each molecule. The greater the electronegativity difference, the more polar the molecule. Additionally, look at the molecular geometry and symmetry of the molecule, as asymmetrical molecules tend to be more polar.
Which electron dot diagram represents a polar molecule?
A polar molecule will have an uneven distribution of charge, resulting in a partially negative and partially positive end. Therefore, an electron dot diagram showing a molecule with an asymmetrical distribution of electrons, where there is a concentration of electrons on one side, can represent a polar molecule.
Can a molecule be polar with no polar covalent bonds?
No, not necessarily. It all depends on the symmetry of the molecule. Take a look at Carbon dioxide. It has a linear shape like this : O=C=O Although the bonds are obviously polar, the molecule is symmetrical. This makes the polarities of the bonds "cancel" each other, so to speak. So overall, this molecule is non-polar. If you take a look at Hydrogen chloride, on the other hand, it has a shape like this: H-Cl The molecule is assymmetrical, so this is a polar molecule.
How do you figure out if a molecule is polar or non-polar?
Find out what the molecules shape is. VSEPR (AXE theory) will help. Look up the electronegativity of the elements that are bonding. Draw the little charges delta +, delta -) the more electronegative element is slightly negatively charged. Then look to see if the "dipoles" on the bonds cancel each other out. If they do its non polar even if the individual bonds are polar. (e.g. CCl4) if they don't its polar, e.g. water.
How can one determine if something is polar?
To determine if something is polar, you can look at its molecular structure and check if it has polar bonds or an uneven distribution of charge. If the molecule has polar bonds or an uneven distribution of charge, it is considered polar.
Is ascorbic acid polar or nonpolar?
Polar. I just answered this question on Mastering chemistry.
Why is bromine polar?
Bromine is a polar molecule because it contains two different atoms (bromine and hydrogen) with different electronegativities. This causes an uneven distribution of electron density, resulting in a slight negative charge on the bromine atom and a slight positive charge on the hydrogen atom, making the molecule polar.
Why is H2O an example of polar molecules?
H2O is a polar molecule because it has a bent molecular structure with oxygen being more electronegative than hydrogen. This causes an unequal sharing of electrons, resulting in a partial positive charge on the hydrogen atoms and a partial negative charge on the oxygen atom, creating an overall dipole moment in the molecule.
How can you determine if something is polar?
To determine if something is polar, you can look at its molecular structure and check if there is an uneven distribution of charge. If there is a separation of positive and negative charges within the molecule, it is considered polar.

Does urea contain polar bonds?
The structure of urea determines its polarity. The C=O portion of the molecule is polar, as well as the two N-H bonds on the opposite end. Therefore urea is a polar molecule. Refer to the related links for an illustration.
Is a molecule polar when it is covalently bonded atoms share elcetrons equally?
tHERE ARE SUCH THINGS AS POLAR COVALENT MOLECULES. LOOK IT UP IN THE LIBRARY CHEMISTRY SECTION. I JUST FINISHED THAT CLASS IN COLLEGE. BECAUSE OF THE ACTUAL SHAPE THE MOLECULE CAN TAKE, IT MAY MAKE IT POLAR. LIKE I SUGGESTED, LOOK IT UP IN A TEXT BOOK IN YOUR LIBRARY NEAR YOU. IT'S LISTED UNDER POLARITY OF MOLECULES.
