Chapter 2.5, Problem 16P

Which of the following compounds is the stronger base? Explain. or NH3 is a v base than NCI3. This is due to the difference in the electron withdrawing strength of Cl compared with H. v is more electronegative than and will v more electron density v the nitrogen than Thus, the nitrogen atom in NCI3 has a v positive charge than it does in NH3. The v positive charge means that is v difficult to add H* to NCI3 than it is to add H* to NH3. Is the compound Sb(OH)5 likely to be acidic, basic, or neutral in water? Justify your answer. Phosphorus and arsenic form acids of the form X(OH)n, so one would predict that antimony would be similar as it is in the same family. Based in the number of OH groups present, it should be However, antimony hydroxides are not stable and form oxides which are known to be amphoteric. Thus, Sb(OH)6 is in fact more likely to be

[References] Compare the structures of HNO2 and H2 CO3. Which would you expect to be the stronger acid? Why? O Nitrogen has a greater electronegativity than carbon. Thus, H-O bond in HNO2 is more polar than in H2 CO3, and HNO2 is the stronger acid. O Nitrogen has a smaller radius than carbon. Thus, H-O bond in HNO2 is shorter than in H2 CO3 , and H2 CO3 is the stronger acid. O Nitrogen has a smaller radius than carbon. Thus, H-O bond in HNO2 is shorter than in H2CO3 , and HNO, is the stronger acid. O Nitrogen has a greater electronegativity than carbon. Thus, H--0 bond in HNO2 is more polar than in H2 CO3, and H2CO3 is the stronger acid. Submit Answer Try Another Version 1 item attempt remaining
