Question

BF4 structure according to coordinate covalent bonds​

Answer 1

According to coordinate covalent bonds​, the molecular geometry of $BF_{4}$ is Tetrahedral.

• Boron has 3 valence electrons.
• Each of the four fluorides contributes one electron to the covalent bond
• There is an overall negative on the molecule that contributes another electron.
• Hence, we have, 3+4+1=8 electrons and $BF_{4}$ forms a Tetrahedral structure.

Hence, the molecular geometry shape of $BF_{4}$ is Tetrahedral.
