To determine base strength you need to look at the pKa value for the molecules conjugate acid (add an H+ to the molecule). If the conjugate acid has a low pKa (strong acid) then the original molecule is a weak base...and high pKa=strong base.
Well I know (atleast I think) the integrations;
1st graph: 2:3:2:2:3; One degree of unsaturation
2nd graph: 1:3:2:3:3; One degree of unsaturation
3rd graph: 1:3; One degree of unsaturation
But then I can't put everything together. I spend atleast an hour one each of these but can't figure...
Homework Statement
I have a 3 compounds with the same formula: C6H12O2
I need to find the molecules by interpreting the H NMR spectroscopy

y*2xcos(x2) dx/dx + sin(x2)*1 dy/dx = 0
2xy cos(x2)*dy/dx = -sin(x2)
What I notice is that you separated sin(x^2)dy/dx by subtraction..which is obviously "illegal"
Try isolating the term with dy/dx in it and then try to isolate just the dy/dx

Well can you list the various tests that I can try to apply
I understand the a_{}n+1/a_{}n test where if the ratio is > 1 and it is bounded about then the sequence converges and < 1 and bounded below then it converges. But I don't understand the reasoning behind the other ones.
Those...
Can somebody please explain to me:
How both series and sequences converge, and the various tests to find out.
I've tried searching but it seems impossible to get any explanations as to why you do the specific test.
