Question

Which of the following sets contain isostructural molecules? I. \[ H_2O,\ OF_2,\ SCl_2 \] II. \[ CO_2,\ BeCl_2,\ HgCl_2 \] III. \[ SiCl_4,\ SF_4,\ XeF_4 \]

• A. I, II, III
• B. I, III only
• C. II, III only
• D. I, II only

Hint:

Common molecular shapes: \[ AX_2E_2 \rightarrow \text{Bent} \] \[ AX_2 \rightarrow \text{Linear} \] \[ AX_4 \rightarrow \text{Tetrahedral} \] \[ AX_4E \rightarrow \text{Seesaw} \] \[ AX_4E_2 \rightarrow \text{Square Planar} \] Molecules having the same shape are called isostructural.
