1.	Can phosphorus with other electronic configuration 3s^(2) 3p^(3) from PH_(5)?
Answer» Solution :Although P shows oxidation STATES of +3 and +5 , it cannot FORM `PH_(5)` . Due to high `Delta_(H-H)`(435.88 KJ `mol^(-1)`) and slightly negative `Delta`eg H(-73 KJ `mol^(-1)`) dihydrogen acts only as a weak oxidising AGENT. Therefore, it can oxidise P to +3 oxidation state but not to its HIGHEST oxidation state of +5 . Thus, P forms `PH_(3)` but not `PH_(5)`
