Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

If a molecule has four electron domains, with two being lone pairs, what is its predicted molecular shape and approximate bond angles?

💡 Hint: Think about how the lone pairs influence the geometry.

Challenge 2 Hard

A compound with a trigonal bipyramidal geometry states that it has no lone pairs. Given this information, what can you infer about its symmetry and overall polarity?

💡 Hint: Consider how bond dipoles' symmetry cancels out.
