WebAs expected, when nitriles are hydrolyzed (by nucleophilic addition of water followed by nucleophile elimination), they form either carboxylic acids or amides, depending on the conditions. General reaction Water is used along with the acid, to provide the reagent for the hydrolysis. Example Webbasic conditions - enolate interemdiate Place the steps involved in the reaction of a carbonyl compound with a halogen under basic conditions in the correct order, starting with the first step at the top of the list 1. base deprotonates the α carbon to produce an enolate 2. the nucleophile attacks the halogen

General reaction Example 1 Mechanism Step 1: Nucleophilic attack by hydroxide Step 2: Leaving group removal Step 3: Deprotonation Contributors Prof. Steven Farmer ( Sonoma State University) WebCommon Conditions: Fischer Esterification Fisher Esterification is best suited for simple alcohols (ex. MeOH or EtOH) which can be used in large excess (as solvent). Primary and secondary alcohols work well, while tertiary alcohols and phenols work poorly. Acid sensitive substrates may not be well tolerated. [1] Examples Mechanism WebCarboxylic esters hydrolyse to the parent carboxylic acid and an alcohol. Reagents : aqueous acid ( e.g. H 2 SO 4) / heat,or aqueous NaOH / heat (known as " saponification "). These mechanisms are among some of the most studied in organic chemistry. Both are based on the formation of a tetrahedral intermediate which then dissociates. hashing calculator crypto
