properties

Dichloromonoxide is a yellow-brown (deep brown as a liquid), unpleasantly strong-smelling gas that is readily soluble in water with the formation of hypochlorous acid . It can only be stored in liquid or solid form at or below -78 ° C. It is sensitive to shock and decomposes in light. It explodes when it comes into contact with organic matter. It forms hypochlorites with alkalis . When diluting a saturated solution, hypochlorous acid is formed .
