According to Bent's rule, in $\mathrm{sp^3d}$ more electronegative element is placed on the axial position, so between $\ce{Cl}$ and $\ce{OCH3}$ in $\ce{SCl2(OCH3)2}$ which should be placed on axial as oxygen is more electronegative, but wouldn't $\ce{CH3}$ reduce its overall electronegativity due to its positive inductive effect?The electronegativity of Oxygen is more than that of chlorine but the negative inductive effect of OCH3 is less than that of Chlorine

But my teacher said that $\ce{OCH3}$ should still be placed on axial position considering electronegativity of oxygen.

Can someone please explain this? Because we are comparing a group's electronegativity (which cannot be found on the Pauling scale) to that of an atom.

  • $\begingroup$ This post does not explain why OCH3 is placed at axial...I have seen this post before and found it to be giving a conceptual understanding of Bent's rule at a basic level but my question is slightly different $\endgroup$ Aug 25 '19 at 16:22
  • $\begingroup$ EN of $\ce{O > Cl}$, but -I effect of $\ce{OCH_3^- < Cl^-}$. May I add this point in question? $\endgroup$ Aug 25 '19 at 17:23
  • $\begingroup$ Thanks for the suggestion have added that in question...am hoping for a proper answer to this now $\endgroup$ Aug 27 '19 at 7:11
