- Structure of sty with lone pair in equatorial position 3-D structure with lone pair in of SF4 axial position
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...

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...
DISCUSSION QUESTIONS 1. In NO," does one of the NO bond distances differ significantly from the other two? Explain. chemically, why you might expect one bond distance to be different. (Hint: Draw a Lewis Structure for NO,':) How is it chemically possible for all of the bond distances in this ion to be the same?
