Well! First some facs - H2 bond disocciation energy is 432 kJ/mol. This is greater than HCl (428 kcal/mol) so the simple statement is false.
Pauling put this idea forward, he analysed bond strengths in terms of valence bond theory and the idea of resonance between a pure covalent bond and an ionic bond. Where the energy of the pure covalent and ionic was very close together there was a considereable strengthening of the bond. In the simple case of the hydrogen halides this criterion was met most closely by HF and the bond energy of this highly polar molecule was stronger than both the pure covalent or pure ionic forms.
Pauling "invented" the concept of electrnegativity through this method of analysing bond strengths.
What else can I help you with?
If two covalently bonded atoms are identical the bond is identified as?
If two covalently bonded atoms are identical, the bond is identified as a nonpolar covalent bond.
Is a covalent bond considered polar or nonpolar?
Both actually. It just depends on the electro-negativity of the atoms bonded together. If both have the same electro-negativity, it is a nonpolar covalent bond. Otherwise, you have a polar covalent bond.
What happens when a polar covalent bond and a nonpolar covalent substance combine?
When a polar covalent bond and a nonpolar covalent substance combine, they may form a heterogeneous mixture where the polar and nonpolar components do not mix together. The polar and nonpolar substances will tend to separate due to their differing intermolecular forces.
What is stronger non polar covalent or polar covalent?
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.
What type of bond is ammonia?
The bonding in ammonia, NH3 is a nonpolar covalent bond.

Is HCN nonpolar covalent bond?
This molecule contains polar covalent bonds.

The bonding in ammonia, NH3 is a nonpolar covalent bond.
What are the two subtypes of covalent bond?
nonpolar bond and polar bond are the two subtypes of a covalent bond
Is O2 an example of a polar covalent bond or nonpolar covalent bond?
O2 is an example of a nonpolar covalent bond. In an O2 molecule, the oxygen atoms share electrons equally, resulting in a balanced distribution of charge and a nonpolar molecule.
When atoms in a covalent bond share electrons unequally the bond is said to be...?
nonpolar scano:)
Is there a polar bond in ch4?
C-H bond of it is polar.CH4 has four such bonds
Is a covalent bond considered polar if the two atoms share the electrons equally?
No, a covalent bond is considered nonpolar when the two atoms share the electrons equally. If the electrons are not shared equally and there is an unequal distribution of charge, then the bond is considered polar.
Is BF3 non polar covalent polar covalent or ionic bond?
BF3 has a nonpolar covalent bond because the electronegativity difference between boron and fluorine is not significant enough to create a polar covalent bond. In a nonpolar covalent bond, electrons are shared equally between the atoms involved.
