Question

Part A

Using the VSEPR model, the electron-domain geometry of the central atom in BF3 is ________.

Answer 1

The electron-domain geometry of the central atom in BF3 is trigonal planar, with the three fluorine atoms at the vertices of an equilateral triangle and bond angles of 120°.

Step-by-step explanation:

Part A: Using the VSEPR model, the electron-domain geometry of the central atom in BF3 (boron trifluoride) is trigonal planar. This means that the fluorine atoms are positioned at the vertices of an equilateral triangle around the central boron atom, with the F-B-F bond angles equal to 120°.

There are three bonding pairs of electrons around the boron atom, with no lone pairs, which leads to this geometric arrangement. All the atoms in BF3 lie within the same plane, resulting in a symmetrical trigonal planar shape.

The electron-domain geometry of the central atom in BF3 is trigonal planar. The fluorine atoms are positioned at the vertices of an equilateral triangle, and the F-B-F angle is 120°. The molecule is highly symmetrical, so the dipoles cancel each other out, resulting in a net dipole moment of zero.
