Tabun

4. Tabun

One of the first nerve agent discovered, this liquid is known for a fruity odor and can be sprayed as a mist that causes convulsions and paralysis. Tabun itself is not extremely deadly, but the success of this chemical compound in war led to the development of deadlier toxins like ricin and soman. Iraqi soldiers used Tabun in the final days of the Iron/iraq to kill thousands of Iranians.


Tabun or GA is an extremely toxic chemical substance. It is a clear, colorless, and tasteless liquid with a faint fruity odor. It is classified as a nerve agent because it fatally interferes with normal functioning of the mammalian nervous system.
  • Formula : C5H11N2O2P
  • Density : 1.09 g/cm³
  • Boiling point : 240 °C
  • Melting point : −50 °C (−58 °F; 223 K)
  • Main hazards : Highly toxic. Fires involving this chemical may result in the formation of hydrogen cyanide
  • Appearance : Colorless to brown liquid.
  • Molar mass : 162.13 g/mol
  • Vapor pressure : 0.07 mm*Hg (9 Pa).
Tabun or GA is an extremely toxic chemical substance. It is a clear, colorless, and tasteless liquid with a faint fruity odor. It is classified as a nerve agent because it fatally interferes with normal functioning of the mammalian nervous system. Its production is strictly controlled and stockpiling outlawed by the Chemical weapons convention of 1993. Tabun is the first of the G-series nerve agents along with GB (sarin), GD (soman) and GF (cyclosarin).
Although pure tabun is clear, less-pure tabun may be brown. It is a volatile chemical, although less so than either sarin or soman.
Tabun can be destroyed with bleaching powder (calcium hypochlorite), though the poisonous gas cynogen chloride is produced.
Tabun became the first nerve agent known after a property of this chemical was discovered by pure accident in January 1936 by the German researcher Gerhard Schrader. Schrader was experimenting with a class of compounds called organophosphates, which kill insects by interrupting their nervous systems, to create a more effective insecticide for IG Farben, a German chemical and pharmaceutical industry conglomerate, at Elberfeld. He discovered that tabun, as well as being a potent insecticide, was enormously toxic to humans.

Betrachotoxin

1. Betrachotoxin  Betrachoxin is most dangerous chemical in the world. It was named by scientists John W Daly and Burnhard Witkop. who separated  the potent toxic alkaloids fraction and determined its chemical properties.  Batrachotoxin is an extremely potent cardiotoxic and neurotoxic steroidal alkaloid found in certain species of frogs, melyrid beetles, and birds. Batrachotoxin was derived from the Greek word βάτραχος bátrachos "frog". Formula: C 31 H 42 N 2 O 6 LD 50   (median dose):  2 μg/kg; (mouse, sub-cutaneous) Molar mass:   538.68 g·mol −1 Main   hazards:  Highly toxic Chemspider:  10310314 Pubchem   CID:  31958 Density: 1.304 gm/ml. The "poison dart" (or "poison arrow") frog does not produce batrachotoxin itself. It is believed that the frogs get the poison from eating beetles or other insects in their native habitat. Frogs raised in captivity do not produce batrachotoxin, and thus may be handled without risk.

2. VX One of the first chemical WMDs, researchers initially produced VX for retail sale in the 1950s as a Pesticide . Thankfully, your likelihood of coming in contact with VX is extremely low - the world's stockpiles have been destroyed, including the United States' main stockpile in anniston ,AL . VX is the top 2 most dangerous chemical in the world. VX  chemical name  is O-ethyl S-diisopropylaminomethyl methylphosphonothiolate , is hard to detect. It is a clear, tasteless and colourless liquid with a consistency something like engine oil. VX is an extremely toxic synthetic chemical compound in the organophosphorus class, specifically, a thiophosphonate. Boiling point :  298 °C Formula :  C 11 H 26 NO 2 PS Melting point :  −51 °C (−60 °F; 222 K) LD 50   (median dose) :  7 µg/kg (intravenous, rat) Log p :  2.047 Vapor Pressure :  0.09 Pa Molar mass : 267.37 g/mol Density : 1.0083 g/cm.
