1)What would be the viable Lewis structure of I(CF3)CL2? Would the CF3 group be in an axial or equitorial position?
2) The ions isoelectronic with carbon suboxide (C3O2) are N5+ and OCNCO+. Whereas C3O2 is linear, both N5+ and OCNCO+ are bent at the central nitrogen. Why is this? Which isoelectronic structure will have the smaller bonding angle with nitrogen.
Appreciate any help that can be offered.
