The number of species from the following that have pyramidal geometry around the central atom is ________ SO3^2−, SO4^2−, SO3^−, S2O7^2−
- 4
- 3
- 1
- 2
Correct answer: 3
Solution
Three of the given species exhibit pyramidal geometry due to the presence of a central sulfur atom bonded to oxygen atoms and having lone pairs that create a trigonal pyramidal shape, specifically SO3^2−, SO3^−, and S2O7^2−.
