Polar compounds such as H20 have a dipole moment associated with the compound, where as compounds like CH4 have no net dipole.
think of the bonds and nonbonding electrons as ropes pulling on the central molecule, if there is an even 'pull' then the compound will be non-polar, for example CO2 has a dipole from Carbon to both Oxygens, but the two dipoles will cancel. NH3 on the other hand will not cancel out because the bonds are not flat but are tetrahedral in geometry because of the non bonding electrons, so NH3 will have a dipole moment.
Polar molecule are more eassily dissociated in water as compair to non polar compound. Eg. HCl and Cl- 2
mostly they are separated by dissolving in a polar solvent as water then filtration and evaporation give two fractions.. .
Polar lipids form bilayers spontaneously in water while non-polar lipids face towards the "non-polar" side of the cell being non water-soluble.
the polar one is less stable than the non-polar one
It just means a non-polar bond. If the difference in electronegativity between the two elements is less than .5, then it is a pure (non-polar) covalent bond.
Non-polar. The electronegativity difference is 0.2 which is non-polar covalent.
It just means a non-polar bond. If the difference in electronegativity between the two elements is less than .5, then it is a pure (non-polar) covalent bond.

In a non-polar covalent bond the sharing of electrons between the atoms is equal.This depends on the difference between the electronegativities involved in the bond; when a difference don't exist or is minimal the bond is non-polar.As an example the diatomic hydrogen bond is 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.
The difference in electronegativity between S and N is only .5, so it's slightly polar. However, it's not very polar.
Since polar molecules have a difference of electronegativity of 0.5-1.7 and non-polar molecules have between 0-0.5, with nitrogen monoxide having a difference right in between, the moloecule can be considered a non polar or polar molecule. But if considered a polar molecule it must be noted that the unequal distribution of electrons is extremely slight.
SeCl4 would be non-polar covalent, because the electronegativity between Se and each Cl would be about the same. They differ by about 0.6. Don't multiply the the electronegativity by 4, because you want to find the difference between each Se---Cl bond. A polar molecule would have an electronegativity difference of less than 2. Electronegativity values are not something you memorize you always have to look them up
Ionic bond: the difference between electronegativities of the atoms is over 2.Covalent polar bond: the difference between electronegativities of the atoms is under 2.Covalent non-polar bond: the difference between electronegativities of the atoms is cca. zero
Non-polar. The electronegativity difference is 0.2 which is non-polar covalent.
