Question
Diisobutylaluminum hydride (DIBALH) can be used to carry out which of the following conversions? A) ester to aldehyde B) carboxylic acid to ester C)2 degree alcohol to ketone D) aldehyde to carboxylic acid E) ester to ketone Which of the following reagents will quantitatively convert an enolizable ketone to its A) lithium hydroxide B) lithium diisopropylamide C) methyllithium D) diethylamine E) pyridine The Hell-Volhard-Zelinsky reaction involves ______. A) the alpha-bromination of carboxylic acids B) the alpha-bromination of ketones C) the bromination of alcohols D) the oxidation of aldehydes to acids E) none of the above The product of the following reaction is a A) semicarbazone B) oxime C) hydroxylamine D) schiff base E) enamineExplanation / Answer
9) DIBAL is used for the conversion of ester in to aldehydes
10) Lithium diisopropyl amide can quantitatively convert an enolizable ketone to its enolate salt generating lithium enolate
11) Hell volhard zelinsky reaction is used for the alpha bromination of carboxylic acids using phosphorus and bromine
12) Ketones generally react with secondary amines to form enamine, so the product of the given reaction will be an enamine
