Which compound has both ionic and covalent bonds?
SO3, C2H5OH, NH4Cl
What is NH4Cl?
Draw C6H6.
see Hansen
Draw the dot structure for CO2 and SO2.
see Hansen
Which of the following has the highest lattice energy? and why?!
MgO, CaO, CsBr
What is MgO? Think distance and charge!
True or False...all carbon/carbon bonds in C6H6 have equal length. EXPLAIN
TRUE. Resonance delocalizes the pi electrons.
Why do CO2 and SO2 have different molecular geometry?
lone pair on central atom in SO2!
Which would have the "deepest dip" in its PE curve? N2, H2, O2 ...and why?
N2 because of its triple bond
Draw N2O dot structure AND make sure formal charge is minimized (use N-N-O as order of atoms).
N (triple) N (single) O
Draw C2H2. What is the molecular geo AND hybridization on each carbon?
linear AND sp
Is the nitrate ion a resonant structure? DRAW IT and explain.
Non-Polar...did you include [ ] and charge?
Which of the following has a resonant AND bent molecular geometry? DRAW IT!
CO2, O3, CH4, OF2
O3
Li2, O2, N2, F2
N2
