WebDetermine the bond energy of the H-Cl bond given that the bond energy of the H-H bond is 434 kJ/mol and the bond energy of the Cl-Cl bond is 232 kJ/mol. Bond Energies: One of the properties of a covalent bond between two atoms is its bond energy (BE). This is defined as the amount of energy needed to break the bond. WebJan 23, 2024 · Unlike the complex transformations of combustion, the halogenation of an alkane appears to be a simple substitution reaction in which a C-H bond is broken and a new C-X bond is formed. The chlorination of methane, shown below, provides a simple example of this reaction. CH 4 + Cl 2 + energy → CH 3 Cl + HCl.
WebMar 28, 2024 · Hint: Bond energy is the amount of energy required to break one mole of a molecule to its constituent atoms.bond energy, also called the mean bond enthalpy or average bond enthalpy is the measure of bond strength in a chemical bond.
