Question

Hey does anyone know how to get the electronegativity of bonds? For example OCl2 where O=3.5 and Cl=3.2. Thank you

Answer 1

Answer:

The enthalpy of reaction is related to the bond energy as:

enthalpyofreaction=[sumofbondenergyofreactants]-[sumofbondenergyofproducts]enthalpyofreaction=[sumofbondenergyofreactants]−[sumofbondenergyofproducts]

There is no bond involved on the product side as all the products are in atomic form.

Enthalpyofreaction=[2XbondenergyO-Cl]-[0]=420Enthalpyofreaction=[2XbondenergyO−Cl]−[0]=420

BondenergyofO-Cl=\frac{420}{2}=210\frac{kj}{mol}BondenergyofO−Cl=
