Which of the following sets of molecules have the same molecular shape within the set? (Compare the geometrical shape of the arrangement of bonds irrespective of the exact bond angle) A) BeCl2, SCl2, MgCl2 B) CH4, SiF4, SCl4 C) O3, CO2, I3- D) SO2, CO2, ClO2 E) O3, H2O, SCl2

To answer this question, we need to understand the VSEPR (Valence Shell Electron Pair Repulsion) theory, which predicts the shape of molecules based on the repulsion between electron pairs in the valence shell of the central atom.

A) BeCl2, SCl2, MgCl2 BeCl2 is linear, SCl2 is bent, and MgCl2 is linear. So, they do not have the same molecular shape.

B) CH4, SiF4, SCl4 CH4 is tetrahedral, SiF4 is tetrahedral, and SCl4 is seesaw. So, they do not have the same molecular shape.

C) O3, CO2, I3- O3 is bent, CO2 is linear, and I3- is linear. So, they do not have the same molecular shape.

D) SO2, CO2, ClO2 SO2 is bent, CO2 is linear, and ClO2 is bent. So, they do not have the same molecular shape.

E) O3, H2O, SCl2 O3 is bent, H2O is bent, and SCl2 is bent. So, they have the same molecular shape.

Therefore, the answer is E) O3, H2O, SCl2.
