Question
Can phosphorus with inter electronic configuration $3 s^2 3 p^3$ for $\mathrm{PH}_5$ ?
Give reason.
✓
Answer
No, phosphorus can not form $\mathrm{PH}_5$ because $\mathrm{H}_2$ is not a good oxidising agent. It can not provide energy for excitation of electron to 3 d -orbital. $\therefore \mathrm{PH}_5$ does not exist.
