To determine the stronger bond, compare the standard enthalpy of formation for the P-Cl bonds in PC13 and PC15. To find the longest bond in a Lewis structure, add the bonds between the atoms and compare their lengths.
The strength of a chemical bond can be determined by comparing the standard enthalpy of formation values. The higher the standard enthalpy of formation, the stronger the bond. In this case, you need to compare the standard enthalpy of formation for the P-Cl bonds in PC13 and PC15. The bond that has a higher standard enthalpy of formation is the stronger bond.
To complete the Lewis structure and determine the longest bond, you need to add bonds between the atoms given in the structure. Once you have added the bonds, you can compare their lengths to find the longest bond.
The question probable may be:
What method can be employed to assess the strength of chemical bonds in molecules such as PCl3 and PCl5? Specifically, how does comparing the standard enthalpy of formation for the P-Cl bonds in these compounds help in determining the stronger bond? Additionally, explain the approach to identifying the longest bond in a Lewis structure, considering the bonds between atoms in molecules like PC13 and PC15
