Question

Describe the shape of the following species:

SiF₄

Answer 1

1. The shape of SiF₄ is tetrahedral.
2. Silicon (Si) is the central atom with four fluorine (F) atoms bonded.
3. It involves sp³ hybridisation of the central silicon atom.
4. The bond angle between \[\ce{F - Si - F}\] is approximately 109.5°.
5. No lone pairs are present on Si, so the shape remains regular tetrahedral.
