Application
Potassium hydride can be used for following applications:
- Deprotonation: As a strong base, potassium hydride effectively deprotonates hydroxyl groups of monomers, generating alkoxide ions. These ions facilitate the ring-opening polymerization of monosubstituted oxiranes.
- Strong Base in Williamson Ether Synthesis: It is employed to generate alkoxides from alcohols, which subsequently react with alkyl halides to form ethers.
- Reducing Agent: Potassium hydride can reduce hindered boranes and borates to trialkyl borohydrides. It also facilitates the reduction of ketones and alkyl halides.
- Alkylation and Enolate Formation: It aids in the formation of enolates from ketones, which can be utilized in one-pot alkylation-cyclization reactions.

Although the response of plants exposed to severe drought stress has been studied extensively, little is known about how plants adapt their growth under mild drought stress conditions. Here, we analyzed the leaf and rosette growth response of six Arabidopsis
