WebJul 6, 2024 · Why does chlorine have a high boiling point? Chlorine, as chlorine has fewer electrons shells than bromine. As a result, chlorine is smaller and has a smaller atomic radius. The difference in size, relates to boiling point of the molecule. This is because the size effects the strength of the forces between the molecules (intermolecular forces). WebThe protection from toxic gases with low boiling point, high volatility, or small molecular weight, such as hydrogen cyanide (HCN), cyanogen chloride (CNCl), phosgene (COCl 2), mainly depends on the chemical adsorption or reaction of metal oxides impregnated on the activated carbon surface; For chemical warfare agents with high boiling point ...
