Part B. Activities of Halogens In the spaces below, write the color you observed for each of the halogens in hexane. These colors will allow you to determine if a reaction took place in any or all of the three experiments you conducted, and what products were formed. Colorless! Chlorine in hexane Orange Co Bromine in hexane lodine in hexane Purple col Record your observations for each of the three experiments in Table 9-3 and indicate which ele- ment is more active and which is less active.

4. In the blanks below, rank the three halogens you tested in order from least active to most active. Based on the trends in electronegativity observed in the halogen group, is the order of activities you measured consistent with these trends? Explain. (least) (most) 5. Suppose you had mixed chlorine water with a solution of sodium fluoride. What would you expect to happen? Where should fuorine be placed in the activity series for the halogens that you prepared in question 4? Why?
