Question:

The tetra-atomic molecules/ions with different shapes are:

Show Hint

Use VSEPR theory to determine geometry based on number of bonding and lone pairs.

  • \( \text{TeCl}_4, \text{SeF}_4 \)
  • \( \text{CH}_4, \text{PCl}_4^+ \)
  • \( \text{SF}_4, \text{NH}_4^+ \)
  • \( \text{SiH}_4, \text{CCl}_4 \)

The Correct Option is C

Solution and Explanation

- \( \text{SF}_4 \): Has a see-saw geometry due to one lone pair on sulfur (AX\(_4\)E type).
- \( \text{NH}_4^+ \): Has a tetrahedral geometry with no lone pair on nitrogen (AX\(_4\)).
So, they both are tetra-atomic but have different molecular shapes.
