do we need them for the test?

Yes, molecules with bent/angular structures are something that we went over in class. An example is H2O.

Yes, as stated above I think we do need to know bent structures.

How do we tell if the structure is going to be bent versus linear?

my ta went over bent and sea saw so I'm pretty sure we should be familiarized with them.

BeCl2 has no lone pairs on the central atom, beryllium. The two bonding pairs are on opposite sides of the Be atom to be far away from each other, so the structure is linear. The same goes for CO2; the central atom, carbon, has no lone pairs and to be far away from each other, the bonding pairs are on the opposite sides of the C atom. The structure is linear.

On the other hand, in H2O, there are lone pairs on the central atom, oxygen. H2O is a polar molecule. The bonding pairs and lone pairs repel one another so the resulting structure is bent.

I hope these examples help!
