- Answer G and HWhich one is the incorrect statement regarding mass spectrum? options: The structure likely contains a chlorine atom if the (M+2)+• peak is approximately one-third as tall as (M)+• The relative heights of (M)+• peak and (M+1)+• peak indicate the number of carbon atoms A signal at M-15 indicates the loss of a methyl group and a signal at M-29 indicates the loss of an ethyl group The structure likely contains a bromine atom if the (M+2)+• peak and (M)+• are almost similar in heights In case of alcohols, a signal at m/z = 18 is produced due to the loss of neutral H2O molecule (Dehydration)Which base peak is expected in the mass spectrum of 2,2,3-trimethylbutane? Question 14 options: M-15 peak M-57 peak M-29 peak M-43 peak M-18 peak
