Difference between lialh4 and nabh4
WebOct 10, 2015 · My teacher told - "To reduce carboxylic acid to alcohol, $\ce{LiAlH4}$ is used. But since $\ce{LiAlH4}$ is an expensive reagent, it is commercially reduced by … WebThe key difference between LiAlH4 and NaBH4 is that LiAlH4 can reduce esters, amides and carboxylic acids whereas NaBH4 cannot reduce them. Both LiAlH4 and NaBH4 are reducing agents. But LiAlH4 is a very strong reducing agent than NaBH4 because the Al-H bond in the LiAlH4 is weaker than the B-H bond in NaBH4.

It is only powerful enough to reduce aldehydes, ketones and acid chlorides to alcohols: esters, amides, acids and nitriles are largely untouched. It can also behave as a nucleophile toward halides and epoxides.
WebMar 31, 2024 · So, the rate of formation of H X − is very high from L i A l H X 4, which makes it stronger reducing agent. On the other hand, Di-isobutyl Aluminium Hydride is a pure covalent compound. It is difficult for it to donate reducing H X −, and after donation also, it can't get any extra stabilisation. Thus, eventually, it becomes weaker reducing ...
