<h1>1 Given the following chlorine-containing compounds: BrCl, Cl2, ICl, LiCl. Arrange these compounds in order of increasing bond polarity.</h1>
<p>A. Cl2<LiCl<ICl<BrCl B. LiCl<BrCl<ICl<Cl2 C. Cl2<BrCl<ICl<LiCl
D. BrCl<ICl<Cl2<LiCl</p>
<h1>2 A molecule has the chemical formula XY3 (3 is a subscript). Y is more electronegative than X. In order for this molecule to be nonpolar, its molecular geometry must be--</h1>
<p>A. triangular planar B. triangular pyramid C. triangular bipyramidal D. T-shaped</p>
<h1>3 The Lewis Structure for AsH3 (subscript 3) predicts:</h1>
<p>A. sp2 hybrid orbitals for the central As atom
B. a total of ten valence electrons
C. a triangular pyramid molecular geometry
D. a molecule without a dipole moment
(For this one, i think she said all are wrong so we have to make A,B,C,D, true?)</p>
<h1>4-- last one :)</h1>
<p>One molecule that does NOT possess an octect of electrons around the central atom would be
A. CO2 B. NO2 C. SO2 D. SiO2</p>
<p>uhh yeah i agree with mine is different...
i would say Cl2, ICl, LiCl, BrCl.</p>
<p>Chloride with Iodide would have less polarity than with Lithium. Lithium is farther away, but it all depends on electronegativity values (which i don't know off the top of my head!)</p>
<p>ok yeah just looked it up (electro #'s)... Chlorine is 3.0, Lithium is 1.0 Iodide is 2.5. the difference between Cl and Li is 2 and the diff from I to Cl is .5.</p>
<p>2>.5 so LiCl has to be more polar than ICl.</p>
<p>or just look at it this way... salts (metal + non-metal) like LiCl have higher polarities than covalent (just non-metal) compounds like ICl.</p>
<p>or you can just put down A and get it right, with no protest.</p>
