Multiple-choice questions may continue on the next column or page – find all choices before answering. 00110.0 pointsThe theory used to explain the behavior ofsolids, liquids and gases is1.the molecular theory. 2.the kinetic-molecular theory.correct3.the VSEPR theory.4.the atomic theory. Explanation: 002 10.0 points Which one of the following statements doesNOT describe the general properties of liq-uids accurately? 2.Aliquidsamplehasacharacteristicvolume that does not change greatly withchanges in pressure.3.Aliquidsamplehasacharacteristicvolume that does not change greatly withchanges in temperature, assuming that theliquid is not vaporized.4.Liquids diffuse only very slowly whencompared to solids.correct5.Liquids have high densities compared togases. O HHOHHABWhich statement is correct?1.The hydrogen bondBis stronger thanthe covalent bond Explanation: A is a covalent bond while B is a hydrogenbond. Covalent bonds are much stronger thanH-bonds.00410.0 pointsAssign the strongest relevant intermolecularforce to the following species, respectively:RbCl2,C6H6(benzene),HI,Fe2O3,CH2NH.I) ionic forcesII) hydrogen bondingIII) dipole-dipoleIV) van der Waals’ forces
padilla (tp5647) – Homework 10 – Sutcliffe – (53770) 2 Explanation:Rubidium Chloride and Iron(III) oxide areboth ion-ion. Benzene is non-polar and thushas only van der Waal’s forces.Hydroiodicacid is polar and has dipole-dipole interac-tions. Methylimine has H-bonding.00510.0 pointsWhat would be the most significant type ofintermolecular forces in a liquid sample offluoroform (CHF3)?
