Olefins

---

(from Latin oleum-oil) (alkenes, ethylene hydrocarbons) - unsaturated acyclic hydrocarbons containing one double bond С = С. The general formula is CnH2n. The carbon atoms at the double bond are sp2-hybridized and form s- and p-bonds. Sodium hydroxide (lat.Nátrii hydroxídum; other names - caustic soda, caustic soda, sodium hydroxide) is an inorganic chemical, the most common alkali, with the chemical formula NaOH. About 57 million tons of sodium hydroxide are produced and consumed annually in the world.
