You may recall that hydride is the conjugate base of hydrogen (H2) (pKaabout 36), making it a very strongbase. NaBH4reacts with water and other weak acids (such as methanol) to generate hydrogen gas (H2). See if you can draw an arrow-pushing mechanism for the formation of H2: Click...
Or I think it’s the second one because in the question it’s not mentioned that ethanol is present as a reagent. As for what I know is that NaBH4 will reduce many organic carbonyls, which include ketones and aldehydes. However it is not a strong enough reducing agent to reduce esters....
Reducing Agent: The donation of the protons to a particular molecule to the formation of a reduced substance will be caused by the reagents, namely reducing agents. Sodium borohydride is a mild reducing agent that can able to r...
Moreover, physical storage uses the physical properties and has physical bond structure, but chemical storage has a strong chemical bond [11]. Compression to the high pressures, such as 350 bar or 700 bar, was the simple and well-experienced method until now. It has short refilling time, ...
Adjacent layers are connected by weak van der Waals forces, and in-plane C and N atoms hybridize with sp2 to form a highly exotic π-conjugated system [24]. The existence of a lone pair of electrons in the N atom provides an opportunity for the coordi- nation of metal atoms. The ...
