Question

what is the geometry of the sef₆ molecule? its lewis structure is

Explanation:

• In the Lewis structure of \(SeF_6\), the central atom \(Se\) is bonded to six \(F\) atoms.
• According to VSEPR (Valence - Shell Electron - Pair Repulsion) theory, when a central atom has six bonding pairs of electrons (no lone pairs in this case as all electron pairs are used in bonding with \(F\) atoms), the molecular geometry is octahedral.
• Tetrahedral geometry occurs when a central atom has four bonding pairs (e.g., \(CH_4\)). Trigonal planar geometry occurs when a central atom has three bonding pairs (e.g., \(BF_3\)).

Answer:

Octahedral
