WebA strong base is a basic chemical compound that can remove a proton (H +) from (or deprotonate) a molecule of even a very weak acid (such as water) in an acid–base reaction. Common examples of strong bases include hydroxides of alkali metals and alkaline earth metals, like NaOH and Ca (OH) 2, respectively. WebIf a strong acid didn’t have a weak conjugate base, then it couldn’t be 100% ionised, so it wouldn’t be a strong acid. The conjugate base of a strong acid must be a weak base. Strong acids, say HCl always exist only as H+ and Cl- in an aqueous solution, HCl doesn’t get reformed. HCl (strong acid) is a very good H+ donor

How do you determine the strongest base in organic chemistry?

WebLeveling effect. Leveling effect or solvent leveling refers to the effect of solvent on the properties of acids and bases. The strength of a strong acid is limited ("leveled") by the basicity of the solvent. Similarly the strength of a strong base is leveled by the acidity of the solvent. When a strong acid is dissolved in water, it reacts with ... WebThe same goes for organic compounds. For example, diisopropylamine or pyridine are common organic bases used in different reactions to neutralize protonated species: However, diisopropylamine is often converted into a stronger base called Lithium diisopropylamide ( LDA) by reacting it with Organo-Lithium compounds: protein biosynthesis wikipedia
