Question

3.Molecules of methane, CH4, and carbon tetrachloride, CCl4, have bond angles of 109.5 degrees, do they have a ________________ molecular geometry shape.

Answer 1

Tetrahedral

Step-by-step 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.
