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
