Try 3 free problems on Lewis structures, geometry, polarity, and intermolecular forces. Want more reps? Premium opens the full 171-problem bank in sets of 3, 9, or 18.
Work these 3 to find out whether bonding patterns are connecting as one system — or whether they still read like a list of separate rules that haven't fully clicked yet.
#4Formal Charge
In the Lewis structure of SO2, the central sulfur atom has 1 double bond and 1 single bond to oxygen, plus 1 lone pair. What is the formal charge on sulfur? (S has 6 valence electrons.)
#5VSEPR Geometry
A molecule has 4 bonding pairs and 0 lone pairs around the central atom. What is its molecular geometry?
#6Lewis Structure + Geometry
Draw the Lewis structure of water (H2O). How many lone pairs are on oxygen, and what is the molecular geometry?
Prep for the test — not just the homework
The 3 free problems show you where you stand. The full bank is how you close the gaps before the test.
Randomized every time — fresh problems that force real understanding, not answer memorization
Full worked solutions — see exactly where your setup went off track, not just whether you were right
171 problems across Lewis structures, VSEPR shapes, polarity, and intermolecular forces
Quick (3), Standard (9), or Extended (18) — use whatever fits your schedule
Filter by type — focus on calculation, concept, or multi-step problems first
Filter by difficulty — dial in easy, medium, or hard problems as you build up
