Explain why lead (IV) alkyl halides can form stable five coordinate complexes more easily than their silicon analogues and comment on the strength of the relevant carbon bonds.
The notable thing is that lead (Pb) is a metal, whereas silicon (Si) is a metalloid.
The size of Pb is more than that of Si.
Hence, Pb can form stable five coordinate complexes more easily than their silicon analogs.
The Pb-C bond is stronger than the Si-C bond.

xplain why chelating ligands give more stable complexes than monodentate ligands; use a balanced chemical equation in your explanation. Explain why macrocyclic ligands give more stable complexes than chelating ligands.
pleas help 5,6,7,8,9,10 III IV 5. The product of free-radical halogenation reactions is an alkyl halide. The major amount of this halide forms during the second step of propagation. However, you should be aware that one possible termination step also forms alkyl halides. Why does the majority of the alkyl halide product come from the propagation step and not the termination step? A. At any given time during the reaction, the concentration of both the alkyl radical and the halide...
Alkyl halides may undergo elimination reactions with BrØnstead-Lowry bases in which the halide and an adjacent proton are lost to form a new π bond. Because of the loss of a proton and a halide anion the reactions are termed ‘dehydrohalogenation’. The two most common associated mechanisms are designated as either unimolecular (E1) or bimolecular (E2) elimination reactions based on reaction rate studies. E1 reactions proceed via a two-step mechanism that involves the cleavage of the leaving group (here the...
Can I-chlorobutane be easily produced from the reaction of 1-butene with HCl and why? (Explain!) (10 pts.) (HINT: You may want to draw out a chemical reaction or two...) 5) Who are there multiple organic or hydrocarbon products produced from the halogenation of alkanes via ultraviolet light? I am grading pretty big on the why part, and it is not only about the number of H's present.....(10 pts.) 6) Using the following monomer, draw the steps and/or mechanism for the...
carbon dioxide has one more resonance(total 3) form than ozone(total 2). can you tell me why this structure is not possible for ozone?
Why does octanol has higher bouling point than water? I belive that water can form 4 H bonds and more polar than octanol. So I expected to see higher boiling point for water. But actually, octanol has higher boiling point than water. Does it imply that octanol has stringer intermolecular force? If so, could anyone explain why?
for question 19 can you explain why you picked the reagents you did? Sterist CH; HC CHH; CCH; - CC CH trans vinylic anion more stable anion able cis vinylic a less stab electron repulsion cis radical anion less stable Hical anion is more stable than the cis radical anion, because the nonbonded electrons are farther apart i The trans vinylic anion is more stable than the cis vinylic anion, because the relatively bulky alkyl group in the trans isomer...
please answer all parts, thanks! 1. More substituted alkenes are more stable than less substituted alkenes. Show the orbital overlap that helps to explain this observation. 2. Why is the heat of hydrogenation for an alkene exothermic? Analyze the bonds that are changing. AH = -30 kcal/mol Explain: + H2 3. Treating alkene "A" below with HBr can lead to a number of products. "A" SM + H-Br A bunch of products. For real, hella products. 3.A. Label the stereocenters...
Read the attached article. Do you feel one style of banking control is more stable than the other? Why? Does one banking method minimize market volatility and risk better or is it just packaged differently? Do you feel the US (Western) Banking system can better control the patterns of behavior going forward that have caused economic damage in the past? Should the Fed continue its stimulus policy, reduce it or abandon it entirely (Google some recent articles to research this)? (Please...
