Is there a limit to how much spacetime can be curved? This is the reason SO 2 has a bent structure. 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. bcmwl-kernel-source broken on kernel: 5.8.0-34-generic. Estimate the As-I bond length from the data in the figure. One of these electrons forms pπ- pπ bond with one oxygen atom and the other forms pπ- dπ bond with the other oxygen. (6)$, on oxygen, thus greatly increasing ionic bonding (roughly from $1*0.5 = 0.5$ to $2*0.(6)=1. Also, since there's an increment in p-character, there's an increment in bond length and thus S-O bond length in$\ce{SO2}$>$\ce{SO3}$. • Chemistry Stack Exchange is a question and answer site for scientists, academics, teachers, and students in the field of chemistry.
