Poisons cyanide

Specific poisonings cyanide, methanol, ethylene glycol, hydrocarbons, volatile solvents, heavy metals, herbicides and pesticides, biological substances (overdose of medicinal drugs is dealt with under individual agents)... 

Particularly hazardous reagents may be charged in limiting amounts. With excess reactants present, the more hazardous reagents should be consumed. This approach is recommended for reactions with the poisonous cyanide reagents and with the explosive sodium azide. The benzyl cyanide 5 was prepared from only 1.05 equivalents of NaCN using PTC (Figure 5.3), and excess NaCN was...

Write the formulas and give the systematic names for ferrous ferrocyanide and ferric ferricyanide. Will intervalence charge transfer occur in these two compounds Kinetically, the Fe(CN)6 ion is inert while the Fe(CN)6 ion is labile. Based on this knowledge, would you expect Prussian blue to be a poisonous cyanide compound Explain. 

The importance of keeping the electron transport system functioning becomes obvious when we consider what occurs in cyanide poisoning. Cyanide binds to the heme group iron of cytochrome oxidase, instantly stopping electron transfers and causing death within minutes ...

Cyanide is another widely known poison. Cyanide (CN ) usually comes in the form of potassium cyanide (KCN), sodium cyanide (NaCN), or hydrogen cyanide (HCN). The first two are white solid, and hydrogen cyanide is a pungent-smelling gas. Cyanide binds very strongly with a metal ion such as Fe(II), Fe(III), Cu(II), Zn(II), and many others. These ions constitute important portions, that is, the active sites of many enzymes and proteins (Chap. 6). When a cyanide ion binds with a metal ion, the enzyme s function is disrupted. Cyanide that enters into our body almost indiscriminately binds to any metal ions and disrupts their functions, but an especially sensitive place is the last enzyme in the whole series of respiratory chain. The enzyme contains both iron (embedded in the porphyrin as in hemoglobin) and copper. Cyanide binds to both iron and copper in this enzyme, and stops its function, the last step of respiration. What is the result It stops respiration hence it stops the production of bodily energy (ATP). As we talked about in Chap. 3, we need to continuously produce ATP. Otherwise, we would die. 

HCN has a faint, bitter, burnt almond-like odor that some people are unable to detect owing to a genetic trait. The volatile compound has been used as inhalation rodenticide and human poison. Cyanide ions interfere with iron-containing respiratory enzymes.
