Hydrogen has an electronegativity of 2.0, while oxygen has an electronegativity of 3.5. The difference in electronegativities is 1.5, which means that water is a polar covalent molecule. This means
The 'LPOP' bond system is possible due to the small size and high electronegative character of the N, O and F atoms, which makes it related to H-Bonding.

Electronegativity is a chemical property which describes how well an atom can attract an electron to itself. Values for electronegativity run from 0 to 4. Electronegativity is used to predict whether a bond between atoms will be ionic or covalent. It can also be used to predict if the resulting molecule will be polar or nonpolar.
Is the covalent bond between O-H in H 2 O the same as the covalent bond between C-H in CH 4 No they are not the same! This is because oxygen has a much higher electronegativity than carbon As a In addition, the chromophores substituted with triazolo[3,4-fr]thiadiazole heterocycle maintains planarity due to the fused rings and thereby favor good [pi]-electron conjugation; improve the optical transparency owing to the presence of large number of high electronegative nitrogen atoms; and provide more oblate ellipsoid shape in the chromophores than that of the prolate shape owing to an Synonyms for Electronegativities in Free Thesaurus.

The electronegativity of an atom, represented by the Greek letter χ (chi), can be defined as the tendency of an atom to draw electrons to itself in a chemical bond. On the Pauling scale, the electronegativity difference between two atoms A and B was defined in terms of the dissociation energies E d of the A-A, B-B, and A-B bonds:
