Which of the following is most stable ?
Options
- AStructure(A)
- BStructure (B)
- CStructure(C)
- DStructure(D)
Correct answer
A. Structure(A)
Step-by-step solution
In (C) and (D) there is l p - b p repulsions. The size of methyl group is greater than F , hence (B) experience greater repulsion than (A). according to bent rule more electronegative atom occupy axial position because axial position has more p- character, so 2 F atoms placed at axial first then rest of F atom occupy equatorial position.
