WebSodium hydroxide is a highly corrosive base and alkali that decomposes proteins at ordinary ambient temperatures and may cause severe chemical burns. It is highly soluble in water, and readily absorbs moisture and carbon dioxide from the air. It forms a series of hydrates NaOH·nH2O. [11] WebAlkynes have physical properties that are similar to alkanes and alkenes. They have relatively low density and low solubility in water. Bonding Alkynes are linear with sp-hybridized carbons. The triple bond is shorter and strong than a double bond and both are shorter and stronger than a single bond.
