Question

Using VSEPR theory, predict the probable structure of \[\ce{ClO^-_4}\].

Answer 1

1. The central atom Cl is surrounded by 4 oxygen atoms.
2. Total electron pairs 4 bonding pairs, no lone pairs on Cl.
3. Electron pair geometry is tetrahedral (since there are 4 pairs).
4. Molecular shape is tetrahedral.
5. Bond angles are approximately 109.5°.
6. No lone pairs, so the shape is symmetrical and tetrahedral.

Hence, (\[\ce{ClO^-_4}\]) has a tetrahedral structure based on VSEPR theory .
