2E.1

On the answer key it states B) may have lone pairs. How can this be if the structure is linear and not bent?

One example where the molecule is linear is in AX2E3, as the electron repulsions cancel out. All of the equatorial domains are electron pairs and the 2 axial ones are in a straight line.

Linear models can either have no lone pairs, or 3 or 4 sets of lone pairs. When the 3 or 4 sets of lone pairs are in the same plane they do not bend the bonded atoms and therefore the overall molecule can still have a linear structure.

AX2E1 (<120) and AX2E2 (<109.5) is bent, AX2E3 and AX2E4 are linear and ~180.
