WebJul 22, 2015 · $\begingroup$ This also explains Charles's confusion about the $\ce{-OR}$ group leaving in ester reduction (in the above comments). The hydride from $\ce{LiAlH4}$ isn't displacing the $\ce{-OR}$ group directly in a substitution-like mechanism, instead it's "only" reducing the carbonyl to a (hemi)acetal, and it's the collapse of the hemiacetal … WebClick here👆to get an answer to your question ️ Alkyl cyanides (CH3CN) when treated with hydrogen in presence of Pt or with LiAlH4 produces same carbon number compound.

The relatively small amount of LiAlH4 present at any one time will reduce the most active … WebMay 31, 2024 · The hydride ion in LiAlH4 is very basic. For this reason, LiAlH4 reacts violently with water and therefore must be used in dry solvents such as anhydrous ether and THF. Like many other strong bases, the hydride ion in LiAlH4 is a good nucleophile, and LiAlH4 contains its own “built-in” Lewis acid, the lithium ion.
