Bond energy



In bond dissociation energy.

Another example: an H bonds in water is 458.9 kJ mol-1, which is the average of the values.

Some bond energy trends (units are in kcal/mol and (mol)) [1]:

H F Cl Br I OH N NH2
bond energies H–X 104 (436) 135 (570) 103 (431) 87 (366) 71 (298) 119 (498) 110 ( 460) —
bond energies CH3–X 105 (440) 109 (452) 84 (352) 70 (293) 56 (236) 91 (382) — 87 (365)

Bond energy/distance correlation

Bond strength (energy) can be directly related to the quadruple bond. This method of determination is most useful for covalently bonded compounds [2].

What determines Bonding Energy

There are several contributing factors but usually the most important is the difference in the electronegativity of the two atoms bonding together. [3]
