The chemical commonly known as tear gas is known as chlorobenzylidene malononitrile (CS). It is a riot control agent that irritates the mucous membranes, causing tearing, coughing, and temporary blindness to incapacitate individuals.
Laughing gas, sometimes called "nos" or "nitrous", is NO2, nitrous oxide. Tear gas refers to several different compounds which may or may not have a general structure.
lachrymator
It is 2-Chlorobenzalmalononitrile.
It's the chemical name for CS gas (tear gas).
The two most commonly used tear gases are ω-chloroacetophenone, or CN, and o-chlorobenzylidenemalononitrile, or CS
The basic constituent of Tear gas is phosgen gas, COCl2 (Carbonyl chloride) and laughing gas is nitrous oxide or N2O.
The common name for methane is marsh gas. Methane is a colorless flammable gas and is the main component of natural gas.
Ethers containing peroxides can be detonate as tear gas when heated. Unburned material may form powerful tear gas. When wet, also forms irritating formaldehyde gas.
CS gas is actually the most common form of tear gas used by law enforcement. It is called CS gas after the two inventors who first synthesized it: Ben Corson and Roger Stoughton. The "CS" stands for the first letters of their last names.
The common name for dinitrogen monoxide is nitrous oxide, often known as laughing gas.
The best known tear gas is "CS" gas- this contains carbon, hydrogen, nitrogen and chlorine.
