Question

Quizplus · Accepted Answer

A tetrahedron has four vertices, and each vertex has three bonds extending to neighboring atoms. The given structure in choice D has four atoms bonded to the central carbon, with a bond length of 1 unit and an angle of 109.5 degrees between adjacent bonds. This arrangement is characteristic of a regular tetrahedron, so choice D is the correct answer. The other choices have different numbers or arrangements of bonds, so they cannot be tetrahedral.
