That the electronegativities of the two atoms are substantially different - enough so to cause polarity in the bond. However, the difference in electronegativities is not great enough to cause an ionic bond to be formed.
A nonpolar covalent bond occurs when the electronegativities of the two atoms are similar. This means that the atoms share the electrons equally, leading to a balanced distribution of charge within the bond.
NO is polar. If you compare the electronegativities (how strongly the element pulls on electrons) N 3.04 O 3.44 ( bigger therefore pulls electrons harder) The electrons will be drawn to the oxygen causing it to be slightly negative, and the N to be slightly positive.
There is no general answer to this question: One of the strongest of covalent bonds is that between two nitrogen atoms in a nitrogen molecule, which is non polar covalent. In contrast, a carbon-carbon single bond, also usually non polar covalent, is relatively weak. The polar covalent bond between hydrogen and fluorine in the gas phase is very strong, while a hydrogen-iodine bond is relatively weak.
Sucrose is a polar covalent compound because it is composed of polar covalent bonds. The oxygen atoms in the sucrose molecule have a higher electronegativity compared to the carbon and hydrogen atoms, leading to an unequal sharing of electrons and creating a polar bond.
Trinitrotoluene, commonly known as TNT, contains polar covalent bonds where electrons are shared unequally between atoms. This makes TNT a polar molecule despite having symmetrical structures due to the presence of electron-withdrawing nitro groups, making it soluble in polar solvents.
A nonpolar covalent bond occurs when the electronegativities of the two atoms are similar. This means that the atoms share the electrons equally, leading to a balanced distribution of charge within the bond.
The meaning is a significant difference of electronegativity.

When atoms in a covalent bond have a rather high difference in their electronegativities, the bond is said to be polar covalent. In polar covalent bonds, electrons are unequally shared between the atoms, resulting in a partial positive and partial negative charge on the atoms.
If two covalently bonded atoms are identical, the bond is identified as a nonpolar covalent bond.
A polar covalent bond is formed when the difference between electronegativities of two atoms is 0,4 to 1,7.
(apex!) the electronegativities of the two atoms are NOT equal.
