Question

can phosphorus with electronic configuration 3s2 3p3 form PH5? Explain?​

Answer 1

Answer:

Although phosphorus exhibits +3 and +5 oxidation states, yet it can not form PH5. Because of high ∆H–H and slightly negative ∆ e.g. H (electron gain enthalpy), dihydrogen acts only as a weak oxidising agent. Thus it can oxidise P to +3 oxidation state but not to its highest oxidation state of +5. Hence P forms PH3 and not PH5.
