WebAnswer (1 of 3): I usually like to cut corners on my mechanisms (after all, I did very well and earned the right jk), but here is the full mechanism by base catalysis with excess Lithium Aluminum hydride and water wash (two … WebLiAlH4 is also a base, so the H + of the carboxylic acid is pulled out by the acid-base reaction. When the reaction by hydride reduction proceeds in this state, dianions are formed as intermediates. In dianions, two oxygen atoms are coordinated with Al +. This makes the reduction reaction less likely to occur.
WebA) Carboxylic acids have higher melting and boiling points than other organic compounds of similar molecular mass. B) All carboxylic acids are double in water due to the polar COOH group.

WebThis page looks at the reduction of carboxylic acids to primary alcohols using lithium tetrahydridoaluminate (III) (lithium aluminium hydride), LiAlH 4. The " (III)" is the oxidation state of the aluminium.
