The twoaldohexoses should be identified when D-arabinose undergoes Kiliani-Fischer synthesis. Concept introduction: Kiliani-Fischer synthesis : sugar reacts with aqueous cyanide (NaCN); the cyanide undergoes nucleophilic addition to the carbonyl group of the sugar which yields cynohydrine. The resulting cyanohydrin is heated with water, which undergoes hydrolysis and forms carboxylic acid . These carboxylic acids react itself and formmore stable lactones. Further, lactone is undergoes reduction reaction with a sodium amalgam which yields two aldohexoses. To find : The twoaldohexoses when D-arabinose undergoes Kiliani-Fischer synthesis

Answer 1

Question

Definition Definition Class of organic compounds that contain a carboxyl group ( - COOH ) and has a general formula R - COOH or R - CO 2 H , where R refers to the alkyl, alkenyl, aryl, or other groups. They can undergo different chemical reactions, such as acid-base reactions, esterification, and oxidation. These are essential components of living organisms, playing important roles in metabolic processes, signaling, and as pharmaceuticals.

Can I please get help with this.

Determine if the following salt is neutral, acidic or basic. If acidic or basic, write the appropriate equilibrium equation for the acid or base that exists when the salt is dissolved in aqueous solution. If neutral, simply write only NR. Be sure to include the proper phases for all species within the reaction. N₂H₅ClO₄

Please help me with identifying these.
