The mass spectrum of methyl methanoate 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 methyl methanoate
Methyl methanoate
(methyl formate) C2H4O2,
Interpreting the fragmentation pattern of the mass spectrum of methyl methanoate [M]+ is the molecular ion peak (M) with an m/z of 60 corresponding to [C2H4O2]+, the original methyl methanoate molecule minus an electron, [HCOOCH3]+. The minute M+1 peak at m/z 61, corresponds to an ionised methyl methanoate molecule with one 13C atom in it i.e. an ionised methyl methanoate molecule of formula 13C12CH4O2 Identifying the species giving the most prominent peaks (apart from M) in the fragmentation pattern of methyl methanoate.
