What combination of number of bonds and number of unshared pairs of electrons will result in a bent shape?

Question

1. 4 and 0 2. 3 and 1 3. 3 and 0 4. 2 and 2

Answer 1

Yes, it's very poorly constructed but I think I know what it's asking for. If I'm reading this right, it wants to know what causes a bent shape. A bent shape is a linear shape that is put into a bent shape due to unpaired electrons. These unpaired electrons repel the atoms and create that shape. If the first number listed is the bonds and the other unpaired electrons, then we're getting somewhere. The first and third answer are obviously wrong since they don't list any unpaired electrons so that leaves the 3 and 1 and the 2 and 2. Bent shapes, such as in water, form typically between three atoms. So the answer would be 2 bonds and 2 unpaired electrons.

Answer 2

This is a poorly constructed test question.  Are you talking about the resulting molecule or the resulting orbitals.  Is this organic, inorganic, or biochemistry?  Ambiguity always leads to wrong answers.
