Question

Which of the following species have the same molecular geometry: CO2, H20, BeCl2, and N2O? a) CO2 and N20 only b) H2O and N20 only c) H20 and BeCl2 only d) CO2 and BeCl2 only e) CO2, BeCl2, and N20

Answer 1

CO2 and BeCl2 both have a linear molecular geometry. N2O has a linear structure but is overall bent, and H2O has a bent geometry due to lone pairs on the oxygen atom. Thus, CO2 and BeCl2 share the same molecular geometry.

Step-by-step explanation:

The molecules CO2 and BeCl2 both have a linear molecular geometry, as they do not have any lone pairs of electrons on the central atom and are arranged in a straight line. N2O (nitrous oxide) also has a linear structure at both ends of the molecule but overall has a bent molecular geometry due to the different atoms involved and their arrangement. H2O (water), on the other hand, has a bent molecular geometry due to the two lone pairs on the oxygen, which repel the bonding pairs of electrons, creating a bent shape.

Therefore, the species that have the same molecular geometry are CO2 and BeCl2, since both are linear. This corresponds to option (d) CO2 and BeCl2 only.
