Chapter 6, Problem 6.19P

PROBLEM 6.19 An ionic liquid consisting of a bulky amine cation and chloride anion has a melting point of 41°C. For a green chemistry solvent application, it is desirable to have a melting point below room temperature (25 °C) so energy is not required to heat the compound. The melting point of the ionic liquid can be altered by replacing chloride with a different anion. The anion possibilities are:

F, Se2, O2, and Br.

(a) Write the electron configuration for each of these ions.

(b) Which ions are isoelectronic?

(c) Which ion is the best choice for replacing the chloride ion to make an ionic liquid with a lower melting temperature?
