Reaction hydrazine

WebHydrazide. It reacts with hydrazides, alkoxyamines, and semicarbazides under aqueous, mild conditions to produce hydrazone, oxime, and semicarbazone linkages that are stable under physiological conditions. From: Comprehensive Natural Products III, 2010. View all Topics. WebThe actual yield is the amount of product that we actually obtained from the reaction. In this case, the actual yield is given as 4.0805 g. To calculate the theoretical yield, we first need to determine the limiting reactant. From the given amounts, we can see that 1 g of 3-nitrophthalic acid and 2 mL of an 8% aqueous solution of hydrazine are ...
