網頁The dipole moment of hydrogen sulphide is 0.97 Debye, less than that of H 2 O (1.84 D), meaning that it is a less polar molecule. This is due to the smaller electronegativity difference between H and S making the H-S bonds less polar than O-H. Another consequence of the low polarity of the S-H bonds is that H 2 S molecules do not associate by ...
