welcome back to war! So, last night about sarin...the "system" stayed pretty calm..why? because there's a specific compound that its very dangerouse to make, called "Dimethylmercury is extremely toxic and dangerous to handle. Absorption of doses as low as 0.1 mL has proven fatal.[6] The risks are enhanced because of the high vapor pressure of the liquid. Dimethylmercury passes through latex, PVC, butyl, and neoprene rapidly (within seconds) and is absorbed through the skin." now any spy dies in few hours! How to make it? you don't find that easy..but I got it..."MeI (methyl_iodide) can also be used to prepare dimethylmercury, by reacting 2 moles of MeI with a 2/1-molar sodium amalgam (2 moles of sodium, 1 mol of mercury)
