WitrynaBecause it is a very non-polar molecule, with only carbon-carbon and carbon-hydrogen bonds. It is able to bond to itself very well through nonpolar van der Waals … WitrynaMethyl chloride was measured directly in seawater using a purge and trap system and gas chromatography with electron capture detection. The results indicate that surface waters of the northwest Atlantic are a source of methyl chloride to the atmosphere during late spring/early summer. The average surface concentration was 271 pM ( … Witrynamethyl chloride (CH3Cl), also called chloromethane, a colourless, flammable, toxic gas. Methyl chloride is primarily prepared by reaction of methanol with hydrogen chloride, although it also can be prepared by chlorination of methane.
