Ethanolic silver
WebEthanolic silver nitrate reacts with alkyl halides that will form stable carbocation like a tertiary carbocation. The silver will act as Lewis acid to form the stable tertiary carbocation from T-butyl chloride via Sn1 mechanism. Here, white insoluble (precipitate) silver halide will be formed. The carbocation will react with oxygen atom of ... WebGreen route is an economic, facile and eco-friendly method, employed for the synthesis of various types of nanoparticles, having it as a starting point biological entity, especially as a plant extract. The present study aims to obtain silver nanoparticles (AgNPs) starting from an ethanolic extract of Populi gemmae (Pg), by adjusting the reaction parameters.
