Which of the following is not tetrahedral?

Options

  1. ABF ₄⁻
  2. BNH ₄⁺
  3. CCO ₃²⁻
  4. DSO ₄²⁻

Correct answer

C. CO ₃²⁻

Step-by-step solution

In CO ₃²⁻ ion the C -atom undergoes s p^2 -hybridisation. It has triangular planar structure. While BF ₄⁻, NH ₄⁺ and SO ₄²⁻ have tetrahedral structure.
