Grimm's hydride displacement law

Grimm's hydride displacement law, also known as Grimm's rule, is a principle in chemistry that states that the rate of a chemical reaction between a metal and a hydride (a compound containing hydrogen) is directly proportional to the basicity of the metal. This rule is used to predict the reactivity of different metal-hydride systems and is used to optimize the conditions for certain chemical reactions involving metal hydrides. The rule is named after the German chemist Friedrich Wilhelm Grimm who first proposed it in 1835.
