Hydroxyl radicals are created in the atmosphere by two principal chemical reactions: During daylight hours, a photochemical reaction occurs in the atmosphere where different wavelengths of light interact with water and terpenes (secreted from plants) in the air to produce simpler by-products known as … Meer weergeven The hydroxyl radical is the diatomic molecule OH. The hydroxyl radical is very stable as a dilute gas, but it decays very rapidly in the condensed phase. It is pervasive in some situations. Most notably the hydroxyl … Meer weergeven The unpaired electron of the hydroxyl radical is officially represented by a middle dot, •, beside the O.
