* sp3 hybridization: This means the carbon atom in tetrabromide (CBr4) has four sp3 hybrid orbitals, each forming a single bond with a bromine atom.

* Molecular geometry: The four sp3 orbitals point towards the corners of a tetrahedron, resulting in a tetrahedral molecular geometry. This means the four bromine atoms are arranged around the carbon atom in a three-dimensional shape resembling a pyramid with a triangular base.

Key Points:

* Bond angles: The bond angles in a tetrahedral molecule are approximately 109.5 degrees.

* Symmetry: The molecule is symmetrical, meaning that the bromine atoms are evenly distributed around the carbon atom.
