splitting peaks definition?

[physics]

Explain why:
i) peak A is split into a quarrtet( four peaks)
ii) peak set B is a single peak
iii) peak set C is a triplet

[superflya]

i) coz it just is.
ii) "               "
iii)"                "

lol

[vexx]

I'm assuming this is H NMR?

The number of splits in each peak is caused by the number of adjacent hydrogen atoms located in a nearby environment. Using the rule n+1.

So the one with four splits must be the CH2 molecule attached to the O and CH3, as it is adjacent to the CH3 molecule which contains 3 hydrogens, so using n+1, there are 4 splits.

Same with the others, so the single split is due to the H3C molecule only being attached to a carbon that connects to no hydrogens, therefore it's a single peak (0+1 = 1)

Make sense... I really hope i'm right haha.

iget it splits according to the neighbouring one but WHY is like "grrrrrrrrrrrrrrrrrrr " i dont get it part

Why exactly is that what you mean? I would have thought my reason would have been okay, but you could add in it being on high resolution and 'spin-spin coupling occurs' which is what i described above..

[n.f]

My teacher explains it with Pascal's triangle and also allows ratios for peak areas.

eg.
No. hydrogen                         No. of peaks and ratio of spin coupling sets (no. of hydrogen in adjacent environment +1)
0                            1              0+1=1 peak
1                          1:1             1+1=2 peaks in ratio 1:1
2                         1:2:1           2+1=3 peaks in ratio 1:2:1
3                        1:3:3:1         3+1=4 peaks in ratio 1:3:3:1

Hopefully that makes enough sense, otherwise you can disregard it.

There's a chemical explanation for the peak splitting but it's really more university level. All you need to know for VCE is the n+1 rule really.

soory   yep i get it now
