Phosphine polar bonds
WebMay 12, 2024 · Polarity or Nonpolarity of Phosphine or Phosphorus Trihydrate. PH3 is a polar molecule because it has a bent structure due to lone pairs of electrons and electron-electron repulsion. Due to uneven charge distribution, the lone pair gives a strong dipole moment of 0.58D, making the compound polar.
