Which of the following species have the same shape? (i) CO2 (ii) CCl4 (iii) O3 (iv) NO2-

This is a Multiple Choice Questions as classified in NCERT Exemplar Ans: Option (iii) and (iv) (i) The number of valence electrons in CO2 is 14. The oxygen atom attached to the carbon atom forms a double bond. Therefore, the hybridization of the structure is sp2. Thus, carbon dioxide is linear in shape. (ii) The number of valence electrons in CCl4 is 32. The structure of CCl4 is arranged in a tetrahedral manner. The chlorine atoms are arranged such that the hybridization is sp3. (iii) The number of valence electrons in O3 is 24. The hybridization of the molecule is sp2 and due to the presence of lone pair of electrons on the central oxygen atom and due to the effect of resonance, ozone molecule has a bent shape. (iv) The number of valence electrons in NO2- is 24. The hybridization of the molecule is sp2 and due to the presence of lone pair on the nitrogen atom it attains a bent shape.
