Question: If the bond length of a C-C bond is 1.54 Å, what is the bond energy in kJ/mol if the bond order is 1?

Options:

Correct Answer: 436

Solution:

For a single bond (bond order = 1), the average bond energy is approximately 348 kJ/mol, but for C-C it is typically around 346 kJ/mol.

If the bond length of a C-C bond is 1.54 Å, what is the bond energy in kJ/mol if the bond order is 1?

If the bond length of a C-C bond is 1.54 Å, what is the bond energy in kJ/mol if the bond order is 1?

Step 1: Understand what bond length and bond order mean. Bond length is the distance between two bonded atoms, and bond order indicates the number of bonds between them.
Step 2: Identify that a bond order of 1 means we are dealing with a single bond.
Step 3: Recall that the average bond energy for a single bond (bond order = 1) is around 348 kJ/mol.
Step 4: Note that for a carbon-carbon (C-C) single bond, the typical bond energy is slightly lower, around 346 kJ/mol.
Step 5: Conclude that the bond energy for a C-C bond with a bond order of 1 is approximately 346 kJ/mol.

Bond Length and Bond Energy – Understanding the relationship between bond length, bond order, and bond energy, particularly for carbon-carbon bonds.
Bond Order – Recognizing that a bond order of 1 indicates a single bond, which has a specific average bond energy associated with it.
