A (a) Draw the structures of the species that correspond to each of the peaks A-E in the following mass spectrum of heptane. (b) Identify the M* peak, the M + 1 peak, and the base peak. 100 80 – 60 40 20 D 20 40 60 80 100 120 m/z Relative abundance

Which one is the incorrect statement regarding mass spectrum?   Question 25 options:   In case of alcohols,  M-18 peak is produced due to the loss of neutral H2O molecule  (Dehydration)   The relative heights of  (M)+• peak and (M+1)+• peak is used to calculate the number of carbon atoms   The structure likely contains a bromine atom if the (M+2)+• peak and (M)+• are almost similar in heights   The molecular ion peak (M)+• always represent the base peak    The structure likely contains a chlorine atom if the (M+2)+• peak is approximately one-third as tall as (M)+•

LOD 透过率/% D 12.2 Which compound is consistent with the spectrum shown below? 薄膜法 2000 1500 1000 500 /cm-¹ 4000 (a) 3000 (b) OH HO (c) OH (d) NH₂ 0= (e)
