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)2Explanation: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)?
