a) Predict in which direction the following reactions willproceed. Justify your answers briefly.
I. HCl + NaF ---- HF + NaCl
II. AlBr3 + 3 NaF ---- AlF3 + 3 NaBr
III. Ti(OMe)4 + 2 TiBr2 ---- TiBr4 + 2 Ti(OMe)2
IV. SrS + HgO ---- SrO + HgS
V. [Pt(CN)4]2- + 4 NaCl ---- [PtCl4]2- + 4 NaCN
VI. CoCl2 + CdI2 ---- CoI2 + CdCl2
VII. [Ag(NH3)2]NO3 + 2 NaSCN ---- NaNO3 + Na[Ag(SCN)2]
+ 2 NH3
b) Dimethylmercury, Hg(CH3)2, is one of the strongest knownneurotoxins. Is it safe to mix mercuric fluoride, HgF2, with methyllithium, LiCH3? Explain your decision.
c) Dimethylmagnesium, Mg(CH3)2, reacts violently with water,while Hg(CH3)2 is remarkably stable in aqueous environment. Explainthis observation and provide a chemical equation for the reactioninvolving Mg(CH3)2.
