Which has more bond energy?
Which has more bond energy?
The electronegativity of the two atoms bonding together affects ionic bond energy. The farther away the electronegativity of 2 atoms, the stronger the bond generally. For example, Cesium has the lowest, and Fluorine has the highest and the make the strongest ionic bond (well single bond at least).
What type of bond is Br Br?
Dibromine (Br2) Bond Polarity
| Electronegativity (Br) | 3.0 |
|---|---|
| Electronegativity (Br) | 3.0 |
| Electronegativity Difference | 0 Non-Polar Covalent = 0 0 < Polar Covalent < 2 Ionic (Non-Covalent) ≥ 2 |

How is bond energy dependent on bond length?
The Energy Associated with a Chemical Bond The higher the bond energy, the ‘stronger’ we say the bond is between the two atoms, and the distance between them (bond length) is smaller. For instance, the HO-H bond in a water molecule requires 493 kJ/mol to break and generate the hydroxide ion (OH–).
What is the bond length of H Br?
362 141
Which bond is stronger NH or single bond triple bond?
There is a very strong triple bond between nitrogen atoms in molecular nitrogen. The N=N bond energy of azides is less than half the energy of a triple bond and N-N bonds are quite weak. Single N-O bonds are considerably weaker than N-H bonds.
Which is stronger polar or nonpolar bonds?
Answer: Bond strength is not clearly defined. One may say that polar bonds are stronger because of the coulomb forces involved, but they are soluble in water etc, so the bond can be easily broken, whereas nonpolar bonds cannot be broken so easily although the forces in play are much weaker.
What can break a covalent bond?
Covalent bonds can be broken if energy is added to a molecule. The formation of covalent bonds is accompanied by energy given off. Covalent bond energies can be used to estimate the enthalpy changes of chemical reactions.
What makes a covalent bond stronger?
Bond Strength: Covalent Bonds Stable molecules exist because covalent bonds hold the atoms together. We measure the strength of a covalent bond by the energy required to break it, that is, the energy necessary to separate the bonded atoms. The stronger a bond, the greater the energy required to break it.
