Answer:

. there are no lone pairs of electrons on the central atom.

Step-by-step explanation:

According to the Valence Shell Electron Pair Repulsion (VSEPR) thoery, the shape of a molecule is determined by the number of electron pairs present on the valence shell of the central atom in the molecule.

The number of electron pairs ultimately determines how they will be arranged in space. However, the presence of lone pairs on the central atom causes a greater repulsion of electron pairs and a consequent deviation of the molecular geometry from that predicted by the VSEPR theory. Hence the answer
