Question

what is the vsepr geometry of the molecule? :f--be--f: tetrahedral bent linear trigonal planar

Explanation:

The VSEPR (Valence - Shell Electron - Pair Repulsion) theory is used to predict the molecular geometry. For the molecule \(BeF_2\), the central atom \(Be\) has 2 bonding pairs and 0 lone pairs. According to VSEPR, when the central atom has \(n = 2\) electron - pair groups (bonding pairs in this case) and \(m=0\) lone pairs, the geometry is linear.

Answer:

linear
