WebQuestion: Consider acid base reaction shown below. Assuming that pyridine and acetic acid are mixed in equal concentrations and using pKa values of acetic acid and pKa … Webvalues are determined relying on density functional theory, its related methods such as WB97XD, M062X, B3LYP with 6-31+Gdp and 6-311++Gdp basis sets for three pyridine derivatives, namely isoniazid, nicotinamide and pyridoxine. When investigating the obtained values, the most accurate values are found to be obtained . via
