Why does "nslookup -type=mx YAHOO.COMYAHOO.COMOO.COM" return a valid mail exchanger? Here, in $\ce{SO3}$, we have no lone pairs on the sulfur atom whereas, in $\ce{SO2}$, the central atom has a pair of lone electrons. Also, since there's an increment in p-character, there's an increment in bond length and thus S-O bond length in $\ce{SO2}$ > $\ce{SO3}$. Since bond length decreases as bond order increases, SO3 have a shorter bond length. The algebra of continuous functions on Cantor set. b.

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? Is the S–O bond strength in sulfur trioxide or sulfite anion larger? Thus, latter has less bond length as compared to the former. Vibrations. The SO2 has a bond angle of 120-degree.

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.
