ClO2 has a bent or V-shaped molecular geometry, according to Bristol ChemLabS. The chemical formula for chlorine dioxide is ClO2. At -59 degrees Celsius, the yellowish-green gas crystallises into vivid orange crystals. ClO2 is a strong oxidising agent that is used in water treatment and bleaching.
Chlorine dioxide is a paramagnetic radical because it contains an odd number of valence electrons. A central chlorine atom connects two oxygen atoms via covalent interactions to form the molecule. Chlorine dioxide has two resonance structures: one with a double bond and three electrons, and the other with a single bond and three electrons. With an O=Cl-O bond angle of 117.6 degrees, both resonance structures exhibit a bent molecular geometry. The oxidation of sodium chlorite, or NaClO2, in a laboratory produces chlorine dioxide. The oxidising agent, CL2, reacts with NaClO2 to create chlorine dioxide and NaCl. As an alternative to pure chlorine, chlorine dioxide is used to bleach wood pulp. The amount of harmful organochlorine chemicals created as a byproduct is reduced when chlorine dioxide is used. Chlorine dioxide is less corrosive than chlorine and is more effective at killing dangerous germs found in water, such as viruses, bacteria, and protozoa.
