Which of these compounds would be the best
conductor in the pure liquid (molten) state?
1.H2S
2. H2Te
3.H2Se
4.PCl3
5.NH3
6.RbCl
7.I2
8.methane (CH4)
9.water (H2O)
10. F2
Because, as the electronegativities of the elements, Rb and Cl, indicate this an ionic compound. Meaning that the elements are as ions ( Rb+ Cl-)., which in liquid (molten) state are charges that move freely, making the compound a good conductor of electricity.
