Answer 1

O₃ and NO²⁻ have the same shape.

• CCl₄ has a tetrahedral shape according to the VSEPR theory. In CCl₄ all the chlorine atoms are singly bonded to the central carbon atom at an angle of 109.5 degrees.
• While in CO₂, the oxygen atoms are doubly bonded to central carbon atom at 180 degrees i.e. it is a linear molecule.
• O₃  and NO²⁻ both exhibit trigonal planar structure.

Answer 2

Answer:

O2 and NO2- have the same species.
