Expert Solution

Step 1

Presence of 1Cl atom: gives peak at m/z M and M+2 with 3:1 intensity ratio

Presence of 1 Br atom: gives peak at m/z M and M+2 with 1:1 intensity ratio

Presence of No or even number of N = Even molecular ion peak

Presence of odd number of N = Odd molecular ion peak

Molecular ion peak: Peak at highest m/z

Base peak: peak with abundance
