E)at the corners of a cube

Quizplus · Accepted Answer

In the three-dimensional structure of methane, the hydrogen atoms attached to a carbon atom are aligned at the corners of a tetrahedron. This is because the methane molecule has a tetrahedral geometry and the hydrogen atoms are arranged symmetrically around the carbon atom. Therefore, the correct answer is C, at the corners of a tetrahedron.
