Consider the molecule AX5, where the central atom A has no lone pairs. X represents the outer atoms, all identical to each other. How many of the following statements are correct?
A. The central atom A utilizes its outermost ns orbital, all three of its outermost np orbitals, and two of its (n – 1)d orbitals for bonding.
B. The A-X equatorial bond length is shorter than the A-X axial bond length.
C. Suppose in AX5 a lone pair was to replace one of the X atoms. At least one of the X-A-X bond angles would contract.
D. Suppose in AX5 a lone pair was to replace one of the X atoms. The lone pair would occupy an equatorial position.
E. Suppose in AX5 one of the X atoms was replaced by a larger atom. The larger atom would occupy an equatorial position.
F. The central atom A is restricted to elements in Periods 3, 4, 5, etc…

Select all the statements that correctly explain why lone pairs prefer to occupy equatorial positions in a system with five electron domains. Check all that apply. A larger bond angle leads to more electron repulsion. Alone pair in an axial position will be too far away from the other electron pairs. There is less repulsion between electron domains in equatorial positions. Alone pair in an equatorial position has more space. Do you know the answer? Match each molecular geometry correctly...
