OH Provide a molecular formula that is consistent with the following mass spectrum data. M.. at m/z= 167, relative height«50.0% (M+1)" at me 168, relative height-4.4% 4)Explanation / Answer
Q1
Note that we can clacualte degree of unstauration, mainly accounting species present
let
DOU = (2*C + 2 + N - H-X)/2
where, DOU = degree of unsaturation, C = cabrons, N = nitrogens, H = hydrogens, X = halogens
then
C = 11
H = 8
X = Cl + Br = 2
O = NA
DOU = (2*C + 2 + N - H-X)/2
DOU = (2*11 + 2 + 0 - 8-2)/2
DOU = 7
