Which of the following pairs contains two species with different shapes? A) CO2, BeCl2 B) PO4 3-, S2O3 2- C) NO3-, SO3 D) HOBr, H2S E) NCl3, BCl3
Question
Which of the following pairs contains two species with different shapes?
A) CO2, BeCl2 B) PO4 3-, S2O3 2- C) NO3-, SO3 D) HOBr, H2S E) NCl3, BCl3
Solution
The answer is E) NCl3, BCl3.
Here's why:
A) CO2 and BeCl2 both have a linear shape. B) PO4 3- and S2O3 2- both have a tetrahedral shape. C) NO3- and SO3 both have a trigonal planar shape. D) HOBr and H2S both have a bent shape. E) NCl3 has a pyramidal shape while BCl3 has a trigonal planar shape. Therefore, they have different shapes.
