### 8.73

is the best way to do this question to draw out lewis structures and just know whats going to break and whats going to form?

### Re: 8.73

I find that, when doing bond enthalpy problems, it really helps to draw the Lewis structures because they really help you "visualize" what bonds are there and what is to be broken and formed. Once you have determined what bonds there are to be broken/formed, then using Table 8.6 or 8.7 would be much easier. Table 8.7 shows the mean bond enthalpy for different bonds, such as C-H and N$=$O.
