Consider the molecule SeF2 . What is the molecular geometry and the reason for this shape?
Linear, because it has no lone pairs on the central atom.
Bent, because it has one lone pair on the central atom.
Bent, because it has two lone pairs on the central atom.
Trigonal planar, because it has no lone pairs on the central atom.
