The electron ionization mass spectrum of a small neutral molecule shows a base peak at 27 and a smaller peak at 26 with a relative abundance of 20%. Deduce the structure of the unknown compound. Let's review the results of the previous steps. Step 1: Identify the molecular ion.
Step 2: Look for the presence of Cl or Br based on isotope pattern.
Step 3: If the molecular ion is odd or even, this indicates the number of nitrogens.
Step 4: Examine the largest peaks and calculate the difference from the molecular ion. Look for common alkyl fragments.
Step 5: Draw the structure that best fits the MS data.
Deduce the structure of the unknown compound.
