Question

Amongst \( NO_3^- \), \( SO_3^{2-} \), \( CO_3^{2-} \), \( SO_4^{2-} \) the non-planar species are

• A. \( CO_3^{2-} \), \( SO_3^{2-} \)
• B. \( SO_3^{2-} \), \( SO_4^{2-} \)
• C. \( CO_3^{2-} \), \( SO_4^{2-} \)
• D. \( SO_3^{2-} \), \( SO_4^{2-} \)

Hint:

The geometry of ions can be predicted using VSEPR theory, which explains the non-planarity of \( CO_3^{2-} \) and \( SO_3^{2-} \).

Answer 1

The Correct Option is A

The species \( CO_3^{2-} \) and \( SO_3^{2-} \) are non-planar due to their molecular geometries. \( SO_4^{2-} \) and other species are planar.
