In the molecule Me 2 XCl 2 (where X=main group elements C, Si, Ge, Sn, Pb), the bond angle Cl–X–Cl is smaller than the C–X–C bond angle. With the highly electronegative halogen substituent, Cl, more p character is concentrated on …

WebSep 19, 2014 · 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 S − O bonds and increases the p-character. Also, since there's an increment in p-character, there's an increment in bond length and thus S-O bond length in S O X 2 > S O X 3. I hope this might get you on ...
