Problem 77 gives us the information that a single carbon -carbon bond has a bond energy of 347 kilojoules per mole.
00:10
A carbon -carbon -carbon double bond has a bond energy of 614 kilojoules per mole, and a fluorine -fluorine bond has 154 kilojoules per mole.
00:23
So the problem also gives us the following reaction that looks like this.
00:32
So double bonded carbons, each bound to two hydrogens plus fluorine gas gives us this molecule here.
01:15
Now the problem asks us to figure out the energy of a carbon fluorine single bond.
01:26
So i'll go ahead and label each of the important bonds to consider from the information that we were given.
01:35
Actually, i'll do that in a different color.
01:37
Maybe easier to see.
01:43
So this bond here, the carbon fluorine bond is what we're trying to find.
01:48
And this carbon -carbon -carbon single bond has a bond energy of 347 kilojoules per mole.
02:02
The fluorine -florean bond here is 154 kilojoules per mole...
