The pair of species having an identical shape is:
Correct answer: C. XeF2, CO2
- A. CFl4, SF4
- B. PCl3, BF3
- C. XeF2, CO2
- D. PF5, IF5
Explanation
The correct answer is XeF2 and CO2. Both of these molecules are linear, with bond angles of 180 degrees. XeF2 achieves this geometry through the presence of three lone pairs that occupy the equatorial positions in a trigonal bipyramidal arrangement, resulting in a linear shape for the bonded atoms. CO2 is linear due to the double bonds between carbon and oxygen, which repel each other equally.For the other options: CFl4 is tetrahedral, and SF4 is seesaw-shaped due to one lone pair. PCl3 is trigonal pyramidal due to one lone pair, while BF3 is trigonal planar. PF5 is trigonal bipyramidal, and IF5 is square pyramidal due to one lone pair.

About Chemical Bonding
Chemical bonding explains molecular shape through VSEPR theory and distinguishes sigma bonds from pi bonds. Questions involve hybridization, bond angles, dipole moment and bond energy, including how electron-pair repulsion determines geometry and how bond polarity differs from the overall polarity of a molecule.
