In the coordination compound (nh4)2[fe(oh2)f5], the fe is octahedrally coordinated. (a) based on the fact that f is a weak-field ligand, pre- dict whether this compound is diamagnetic or para- magnetic. if it is paramagnetic, tell how many unpaired electrons it has. (b) by comparison with other complexes reviewed in this chapter, discuss the likely color of this compound. (c) determine the d-electron configuration of the iron in this compound. (d) name this compound.

The compound is paramagnetic. It has four unpaired electrons b) the compound will be green in colour. Ammonium pentaflourido aqua Iron II. Iron has a d-electron configuration of d4

Explanation: Weak field ligands cause weak crystal field splitting leading to the formation of paramagnetic species. Most iron II compounds appear green in colour. In naming ligands, negative ions are named first followed by neutral species. Iron has an outermost electron configuration of 3d4s2 so Fe II is a d4 ion

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.

can you list the answers so i can answer
