Okay, i think in this problem that we are to consider that these are all f2s, and this is cf4, and this is h.
00:17
This would be of2.
00:20
I think that that's what we're supposed to think here.
00:25
And we're going to use the bond enthalpies from a different table.
00:30
So i think i have all of these here.
00:36
Let me see if i've got them.
00:38
In this problem, i have one c triple bond o.
00:52
I have ff.
00:56
Here i have cf.
00:58
I have four of those bonds, and i have three ff bonds.
01:05
Here i have two of bonds.
01:09
Okay, now i'm going to go find the table i need.
01:13
It says to find table 7 .4.
01:18
So let me get to page 460.
01:24
Give me a good start here and see if i can find table 4, 10 .4.
01:33
There's 10 .6.
01:37
There's 10 .5.
01:46
There's not 10.
01:47
There's 10 .4.
01:49
Okay...
