The bond enthalpy of the \(\mathrm{C}-\mathrm{N}\) bond in the amide group of proteins (see Problem 9.81) can be treated as an average of \(\mathrm{C}-\mathrm{N}\) and \(\mathrm{C}=\mathrm{N}\) bonds. Calculate the maximum wavelength of light needed to break the bond.

ANSWER:

Step 1 of 2

The  bond enthalpy of  bond in the amide group is an average value of the bond enthalpy of  bonds.

From the table 9.4(reference  in the textbook)

 The bond enthalpy of  = 276 KJ/mol

The bond enthalpy of  i=  615 KJ/mol

The bond enthalpy of  bond in amide group is,
