**Title: Calculating Bond Dissociation Energy for Propane****Introduction:**The bond dissociation energy is a measure used to determine how much energy is required to break specific bonds within a molecule. In this example, we calculate the energy needed to break all the C-H bonds in a mole of propane (C₃H₈) molecules.**Bond Dissociation Energy Table:**The table below provides bond dissociation energy values for various single and multiple bonds. All values are given in kilojoules per mole (kJ/mol).**Single Bonds:**- H-H: 432- H-C: 411- H-N: 386- H-O: 459- C-C: 346- C-N: 305- C-O: 358- N-N: 167- N-O: 201- O-O: 142**Multiple Bonds:**- C=C (double bond): 602- C≡C (triple bond): 835- C=O: 799- C≡O: 1072- C=N: 615- C≡N: 887- O=O: 494- N≡N: 942**Calculation:**To calculate the total energy required to break all C-H bonds in 1 mole of propane:- Propane has 8 hydrogen atoms resulting in 8 C-H bonds.Using the H-C bond energy:- Energy required = 7 bonds × 411 kJ/mol = 2877 kJ/mol**Conclusion:**By understanding bond dissociation energies, we can better comprehend molecular stability and the energy dynamics involved in chemical reactions. In the case of propane, substantial energy is required to break all its C-H bonds, reflecting its stability as a hydrocarbon.

Bond dissociation energy is the amount of energy required to break 1 mole of the bond into its separated atoms in the gaseous state.The bond dissociation energy of C-H bond is 411 kJ/mol. Since, 1 mole of propane contains total 7 C-H bonds. Hence, the bond dissociation energy (BDE) of 7 C-H bonds is: BDE=411×7=2877 kJ/mol Hence, the bond dissociation energy of 7 C-H bonds in 1 mole of propane is 2877 kJ.
