In which pair of species, both species do have the similar geometry ?
CO2, SO2
CO23- and SO32−
SO42- and ClO4-
PH3 and BH3
The geometry of CO2 is linear.(O=C=O)(O=C=O)
The geometry of SO2 is v-shape
The geometry of CO32- is trigonal planar.
The geometry of SO32− is pyramidal shape
The geometry of SO42− is tetrahedral
The geometry of ClO4− is tetrahedral
The geometry of NH3 is pyramidal shape
The geometry of BH3 is trigonal planar
Hence (3) is the correct answer.
