Fill in m/z values in the [M+2]⁺ column in Model 6.

a. For each compound containing Br or Cl, draw the most common molecule responsible for each peak in that row. Be sure to include isotopic labels for each nonhydrogen atom (The first box is done for you.) (Hint: Look back at the entries for Br and Cl in Model 5.)

b. Fill in the intensities for each box in the [M+2]⁺ column.

c. Why is there no significant [M+2]⁺ peak for the first five rows?

d. What elements other than Cl and Br will generate a noticeable [M+2]⁺ peak?

(Hint: Look at the table in Model 5.)

e. Fill in the blanks in the following two statements:

(1) If the intensities of the [M+2]⁺ and [M]+ peaks are approximately equal, then there is likely one ______ atom in the molecule.

(2) If the intensity of the [M+2]⁺ peak is about one-third that of the [M]+ peak, there is likely one ______ atom in the molecule.
