A molecule with two lone pairs on the central atom and two attached atoms would have the same molecular geometry as a molecule with four atoms attached to the central atom?

• True

• False

Answer explanation

False, because a molecule with two lone pairs on the central atom and two attached atoms would have a different molecular geometry than a molecule with four atoms attached to the central atom.
