The electronegativities of the two atoms are not equal.
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.
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.
The meaning is a significant difference of electronegativity.

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.
(apex!) the electronegativities of the two atoms are NOT equal.
In a polar covalent bond the atoms do not share the electrons equally, whereas in a nonpolar covalent bond the atoms do share the electrons equally.
