Question

how will you predict the basicity of h3po3 and h3po2 from H-nmr spectrum

Answer 1

Answer:

From structure given below we can see H3PO2 has one ionizable -OH group ,thus its basicity is 1 and H3PO3 has two ionizable -OH groups thus it's basicity is 2. 2) Acidity of trioxides of N,P, As i.e Group 15 elements decreases down the group
