Answer:
Tetrahedral
Explanation:
A molecule is tetrahedral if it has a bond angle of 109.5 degrees.
Recall that the valence shell electron pair repulsion theory states that electron pairs on the outermost shell of the central atom in a molecule tend to position themselves as far apart in space as possible.
Hence, when there are four electron domains on the four electron pair position themselves at the corners of a perfect tetrahedron at a bond angle of 109.5 degrees as long as there are no lone pairs present.
