Homework Answers
In mass spectrum the peak with highest m/z value is called as molecular ion peak. That mass is called as molecular ion mass.
Molecular formula of the given compound is C7H13NO.
Molar mass of the compound is,
7(C)+13(H)+1(N)+1(O)
= 7(12)+13(1(+1(14)+1(16)
= 84+13+14+16
=127
The 13C atom M+1 peak molar mass is 128
Hence the molecular ion (M) peak m/z is 127.
Eliminate the spectrums which are not having molecular ion peak at 127.
Therefore the correct option is spectrum A.
