What is the bond energy of a C-H bond?
It takes roughly 100 kcal of energy to break 1 mol of C–H bonds, so we speak of the bond energy of a C–H bond as being about 100 kcal/mol. A C–C bond has an approximate bond energy of 80 kcal/mol, while a C=C has a bond energy of about 145 kcal/mol.
How to calculate bond energy in chemistry?
To calculate bond energy
1
Add together the bond energies for all the bonds in the reactants. – this is the 'energy in'.
2
Add together the bond energies for all the bonds in the products. – this is the 'energy out'.
3
Calculate the energy change = energy in – energy out.
Which bond has the highest bond energy?
The S−S bond has highest energy and highest bond strength For example, the bond energies of S−S and O−O bond are 49 and 33 kcal/mol respectively. As we move down the group from S to Se and Te, the bond energy decreases. Consider the following statements regarding hydrides of VIA group elements.
