We are one of the leading international schools in Kuala Lumpur, proud of our excellent reputation in providing an outstanding and thriving all-round education based on the British curriculum for 3 to 18 year olds. Welcome to Alice Smith School
Electronegativity values are useful in determining if a bond is to be classified as nonpolar covalent, polar covalent or ionic. The electronegativities of oxygen and nitrogen are respectively, 3.44 and 3.04 on the Pauling scale, the electronegativity difference being, 0.4. This is a very small difference and the bond is only very slightly polar, sometimes even considered non-polar. One should make the distinction between a polar/nonpolar BOND, and a polar/nonpolar molecule. You can have a polar bond, such as those in CCl4, but the molecule is non polar because of the molecular geometry and the fact that the 4 chloride atoms cancel each other. NO not only has a polar bond, but the molecule itself is also polar.
If the difference in electronegativity for the atoms in a bond is greater than 0.4, we consider the bond polar. If the difference in electronegativity is less than 0.4, the bond is essentially nonpolar.) If there are no polar bonds, the molecule is nonpolar.
It is a polar molecule
A polar molecule
It is a polar molecule and has polar bonds.
No a molecule is a molecule, polar or nonpolar.
a non polar molecule
No, O3 is not a polar molecule. It is a nonpolar molecule.
Yes, NO is a polar molecule.
it is polar (inorganic) molecule
A on polar molecule is when there is an equal sharing of electrons between the two atoms of a diatomic molecule. There is a symmetrical arrangement of polar bonds on a non polar molecule.
yes, a non polar molecule can have a polar bond, as long as it has another opposite polar bond to counter the first.
No, without polar covalent bonds a molecule can neither be polar.
HBr is a polar molecule
oil is non polar molecule
No, ether is a non polar molecule.
Yes. HI is polar molecule.
Water is a polar molecule.
Water IS a polar molecule.
yes, SO2 is a polar molecule
O2 is non polar molecule .
Yes. chloroform is polar molecule
I think you have a typo in your molecular formula but CH3Cl is a polar molecule and CCL4 is a non-polar molecule
This is a polar molecule.
The two factors are 1) the polarity of the bonds between the atoms in the molecule, and 2) the shape of the molecule. Basically, if the bonds are non-polar, the molecule is. If the bonds are polar, but the molecule is in such a shape that they cancel each other, the molecule is non-polar. If the bonds are polar and the molecule's shape doesn't cause them to cancel, the molecule is polar.
