(0 a mass spectrum (El mode): the peak at m/z = 165 is the molecular ion,
and the peak at 166 has an intensity of 10.2 (relative to M- 100)
(i) a H-NMR spectrum (10% solution in CDCB, 90 MHz) with J values 6-9
Hz, & the integrations are 2:2:4(q + br. s):3 the broad singlet @ 4.1
ppm is exchanged on addition of D2O;
(ii) a 13C-NMR spectrum (CDCb, 25 MHz) with 7 peaks, occurring at
167 (Co), 151 (Ca), 132 (CH), 120 (Ca), 113 (CH), 60 (CH2), & 14 (CH3),
(iv) an IR spectrum.
Analyse the spectra, and identify the compound making sure to show your
logic. Make sure to show clearly how you obtain the molecular formula, and you
should briefly explain the observed fragmentation pattern in the MS.
You should also assign as many peaks as possible in the NMR spectra, and
the principal peaks that you are able to assign in the IR.
