Verified step by step guidance

Understand that carbon typically forms four covalent bonds due to its four valence electrons, seeking to complete its octet.

Recognize that when carbon forms four single covalent bonds, it undergoes sp3 hybridization, which involves the mixing of one s orbital and three p orbitals.

Visualize the sp3 hybridization process, which results in four equivalent hybrid orbitals oriented in space to minimize electron repulsion.

Identify the geometric arrangement of these sp3 hybrid orbitals as a tetrahedron, where each orbital points towards the corners of a tetrahedron, maximizing the distance between them.

Conclude that the three-dimensional shape formed by these hybrid orbitals when carbon is bonded to four other atoms is a tetrahedron, with carbon at the center and the bonded atoms at the vertices.
