Chemistry · CHEMICAL BONDING AND MOLECULAR STRUCTURE

हिन्दी

In \( \text{SF}_4 \), the lone pair of electrons on the central sulfur atom preferentially occupies:

  1. An axial position to minimize bond pair-bond pair repulsion
  2. Both axial positions simultaneously
  3. Any random position as all positions are equivalent
  4. An equatorial position to minimize lone pair-bond pair repulsions at \( 90^\circ \)

Correct answer · Option 4

An equatorial position to minimize lone pair-bond pair repulsions at \( 90^\circ \)

Explanation

In \( \text{SF}_4 \), the lone pair occupies an equatorial position so that there are only two lp-bp repulsions at \( 90^\circ \) instead of three at axial positions.
