Bec ause of the lone pair on oxygen, the structure of \(\ce{H_2O}\) is bent (via VEPSR theory), which that the vectors representing the dipole moment of each bond do not cancel each other out. H2O higher dipole moment than H2S because of the fact that oxygen is more electronegative than sulphur due to which O pulls the electron more than S. 27 Related Question Answers Found What type of bond is h2s? In the case of Cl_2, the 2 atoms are identical, so no polarization of the bond is possible, and the dipole moment is zero. Due to their different three-dimensional structures, some molecules with polar bonds have a net dipole moment (HCl, CH 2 O, NH 3, and CHCl 3), indicated in purple, whereas others do not because the bond dipole moments cancel (BCl 3, CCl 4, PF 5, and SF 6). The oxygen side of the molecule carries a net negative charge, while the side with the two hydrogen atoms has a net positive electrical charge. The vector sum is not zero, and tasteless compound that is vital for every known living process Molecular moments!
