Improve this question. If you look at the link that Whiz gave you, particularly at the part about what influences polarizability, you will see no mention of mass, only a discussion of the number of electrons and references to atomic radius, which will influence the volume over which the electrons are spread. HCL is a polar molecule as chlorine has a higher electronegativity than the hydrogen. 11.26 Rationalize the difference in boiling points in each pair: (a) HF (20 oc) and HCI (-85 00, (b) CHC13 (61 oc) and CHBr3 ion-dipole force Identify the compound that has hydrogen bonding: H2O: Pair of substances that are most likely to form a homogenous solution: Answer = CH2Br2 (Dibromomethane) is Polar What is polar and non-polar? Small amounts are formed naturally by plants in the ocean. What is the strongest intermolecular force present in CHBr3?

Bromoform (CHBr 3) is a brominated organic solvent, colorless liquid at room temperature, with a high refractive index, very high density, and sweet odor is similar to that of chloroform.It is one of the four haloforms, the others being fluoroform, chloroform, and iodoform.Bromoform can be prepared by the haloform reaction using acetone and sodium hypobromite, by the electrolysis … It is only coincidental that bromine is more massive than chlorine, since atomic weight increases along with atomic number. Which of the following molecules has the weakest intermolecular force? I wont answer those, but here are some rules which might help you: 1) There are ALWAYS London Dispersion forces 2) If you can draw a plane through a 3D version of the molecule where one side is partially positive and the other is partially negative, you have dipole-dipole 3) I have never heard of ion-dipole... maybe for mixtures of dipoles (for example, water) and ionic compounds (NaCl). IT WILL HAVE ONLY LONDON FORCES HOLDING IT TO NEIGHBORING CH 4 MOLECULES. http://chemwiki.ucdavis.edu/Physical_Chemistry/Qua... Bromine is a larger molecule therefore more stable giving it a higher boiling point than the CHCl3 sorry I forgot the name for this, but that is the reason. FREE Expert Solution Show answer. Intermolecular forces (IMF) _____ when temperature increases. The increased polarizablility of Br (vs Cl) is due to the number of electrons, not the mass. Intermolecular forces are primarily responsible for: holding together molecules in a material. Rep:? Thus CHBr3, having the greater dipole moment, experiences stronger dipole-dipole attractions and thus has a higher boiling point.
