Explain why phosphine, $mathrm{PH}_{3},$ is less polar than ammonia.
How is phosphine's $\left(\mathrm{PH}_{3}\right)$ structure different from that of ammonia?
Phosphine, $\mathrm{PH}_{3}$, is a hydride of phosphorus as ammonia, $\mathrm{NH}_{3}$, is of nitrogen. Explain why phosphine boils at a much lower temperature than $\mathrm{NH}_{3}$ in spite of having a molar mass twice that of ammonia.
