    Relative is the one when you don't multipty the uncertainity by 100 as u did for % uncertainity!

    (Uncertainityx100)/Original Value = %uncertainity for relative uncertainity you dont multiply it by 100

    you can test propanone but not propanal only aldehyde which gives posotive results is ethanal!!

    The number of peaks splits into equals n+1 where n is the number of H atoms on the adjacent Carbon atom Thanks to littlecloud11 you have prooved to be a big cloud lol Thanks again little explanation: so in the fact n+1 n = total number of H protons in the neighbourhood and you add 1 only once...

    Ch2 have two neighbours with awesome protons(specifically Hydrogen Atoms) each 3 so from both neighbours you get 6 protons now as we know that when we split we apply fact (n+1) where n is the proton in "a" neighbour so we have 2 neigbours so add 2 in 6 you get 8 splits

    Bismillah, MashaAllah a BIG question Ok so i assume you know about Peaks we can deduce the structure by high resolution NMR where the peaks are splits apart Peaks Splitting Depends on(highResolution NMR): the proton environment in the neighbour (lol not in my neighbour) the one which carbon is...

    F=Le L=Avagadro no = 6.02x10^23 e=Charge ~ 1.6x10^-19 u get approx 96500 C/mol i guess
