Problem 35 says to repeat problems 31 and 33 by consulting figure 8 .3 and using actual electronegativity values.
00:12
So problem 31 said to order each of the groups a through d in order of increasing electronegativity.
00:20
So the guess value or the best, the educated guess based on what we know about electronegativity value, across the periodic table was c and then o, carbon, nitrogen, then oxygen.
00:38
So actually looking at electronegativity values, carbon has a value of 2 .5, nitrogen has a value of 3 .0, and oxygen has a value of 3 .5.
01:03
So in terms of real electronegativity values, this guess is actually correct.
01:12
The same goes for b.
01:15
So for selenium, we have a value of 2 .4.
01:22
For sulfur, it's 2 .5.
01:26
And for chlorine, it's 3 .0.
01:33
So again, our guess was correct.
01:37
For tin, germanium, and silicon, however, all of those have an electronegativity value of 1 .8.
01:47
So since they're the same, you can't really necessarily order these...
