Doc Brown's Chemistry Advanced Level Pre-University Chemistry Revision Study Notes for UK IB KS5 A/AS GCE advanced A level organic chemistry students US K12 grade 11 grade 12 organic chemistry courses involving molecular spectroscopy analysing mass spectra of propan-2-ol
Propan-2-ol C3H8O, , , ,
Interpreting the fragmentation pattern of the mass spectrum of propan-2-ol(2-propanol, isopropyl alcohol)
[M]+ is the molecular ion peak (M) with an m/z of 60 corresponding to [C3H8O]+, the original propan-2-ol molecule minus an electron, [CH3CH(OH)CH3]+.
The small M+1 peak at m/z 61, corresponds to an ionised propan-2-ol molecule with one 13C atom in it i.e. an ionised propan-2-ol molecule of formula 13C12C2H8O
Identifying the species giving the most prominent peaks (apart from M) in the fragmentation pattern of propan-2-ol.
