Formula and structure: Chloroform chemical formula is CHCl 3 and its molar mass is 119.37 g mol -1. The molecule has the typical structure of a methane, which is the most related molecule due to chloroform is a methane where 3 hydrogen atoms has been substituted by 3 chloride atoms. Thus, the structure of the chloroform is a tetrahedral. Its chemical structure can be written as below, in the common representations used for organic molecules. Occurrence: Chloroform is found in nature as being produced by some fungi and bacteria in soils and seas. Preparation: Even when chloroform can be found in nature, the total of the solvent used by the industries is synthesized through chemical methods. The first method is the chlorination of the methane or chloromethane until chloroform, and given dichloromethane as side compound. A second strategy is the reaction between a solvent as acetone or ethanol and a chlorinate lime. Physical properties: Chloroform is a colorless liquid with and ethereal odor. Its density is 1.489 g mL -1 and its melting point is -63.5 ºC and its boiling point is 61.15 °C. It is slightly soluble in water and it is soluble in benzene, ditethylether and carbon tetrachloride. Chemical properties: Chloroform is a non-polar solvent due to the molecule has three chlorine atoms (which have a high electronegativity) but these are orientated in opposite directions, thus when the moment dipolar total is low. Moreover, the chloroform is low reactive and thus, it can be u...

It’s definitely good for that, but subversive maneuvers aren’t what it was originally made for. Originally it was used as an anesthetic to knock people out for surgery. It sounds like a handy thing to have in your supplies, right? The problem is that you can’t just walk into your local superstore and pick up a gallon of it from the shelf beside the milk. You can, however, make your own. Chloroform, whether pharmaceutical grade or homemade, is lethal in the wrong hands. Don’t use it without training! That being said, if you have a medically-trained person in your group, knowing how to make it can come in handy in a variety of ways. You can use it to anesthetize people for surgical procedures or to operate on animals for procedures such as castration. It’s also used in pesticides, disinfectants, dry cleaning solutions, photography development, and refrigerators. This is the ...
