In these molecules the difference of the electronegativity between the two atoms is significant.
The answer is yes, because molecules get polarity after forming polar covlent bond,no such polar molecules can exist which do not contain polar covalent bond. Am I right?
H2 contains the strongest polar covalent bond.
The correct answer is POLAR BOND.
Covalent bond.
covalent bond
Particles formed from the covalent bonding of atoms are called molecules.
A+ ionic bond
Generally a polar molecules (as salts) have an ionic bond.
a polar covalent bond
Water molecules form covalent bonds, because they are non-metal compounds. If you mean the bonds within the water molecules themselves, they are Hydrogen bonds.
A bond between two or more polar covalent molecules is called a Dipole-Dipole attraction (or interaction).
Molecules can be polar or non-polar; bonds are what hold molecules together, but they are not in themselves polar or non-polar. I should point out that the most famous polar molecule in the world, the water molecule, does have covalent bonds.
