In this video we saw that salts could be acidic, basic, or neutral in nature. And the nature depends on the nature of the parent acid and base. We saw that what will be the nature of salt if the acid and base both are strong, and what will be the nature if one of them is strong and the other is weak.This causes extensive hydrolysis of cellulose. The use of HNO 3 -NaNO 2 produces OC with 14-18% carboxyl content, but requires a long reaction time. The oxidation of cellulose with a mixture of HNO 3 /H 2 SO 4 -NaNO 2 is faster compared to that with HNO 3 -NaNO 2 alone and allows the production of OC with 16% carboxyl content.

Due to higher electronegativity of O than N atom, O - H bond is more polar than N - H bond. Hence, O - H is more acidic in nature than N - H bond. Now, NH 2 and OH have negative charge due to which they are more basic than NH3 and H20. Question 26.Herein, we report a two-step oxidation–hydrogenation strategy to achieve this goal. In the oxidation step, the O2/NaNO2/DDQ/NHPI system selectively oxidizes CαH–OH to Cα═O within the β-O-4 structure. In the subsequent hydrogenation step, the α-O-4 and the preoxidized β-O-4 structures are further hydrogenated over a NiMo On hydrolysis of a "compound", twocompounds are obtained.
