Explain why : (a) H2S is more acidic than H2O. Here we will provide an explanation of SO2 molecular geometry, SO2 electron geometry, SO2 bond angle, and SO2 Lewis structure. The point, however, is, that in this particular structure more than one effect is in play, and their effects outperform whatever small effects are considered when Bent's rule is applied. There are more significant factors in effect here. In SO2 molecule, the observed bond lengths of two S - O bonds are exactly the same and the length is somewhere in between single and double bond length. Solution for Compare SO2 and (SO4)2−, choose molecule that has shorter sulfur–oxygen bond lengths? How do you take into account order in linear programming?

Thermochemical data for some negative cluster ions of importance in atmospheric ion chemistry have been determined from equilibrium constant measurements in a flowing afterglow apparatus. Making statements based on opinion; back them up with references or personal experience. According to Bent's rule, the lone pairs tend to occupy the orbital with more s-character which in turn decreases the s-character in the $\ce{S-O}$ bonds and increases the p-character.
