You are correct that the CH3Cl bond should be stronger than the CH3I bond but the boiling point of CH3I is higher because the molar mass of CH3I is higher. CH3Br, CH3Cl , CHBr3 and CH2Br2 are all four polar, they have a net dipole moment.

View solution Arrange the following in the increasing order of boiling points: The decreasing order of boiling point of haloalkanes CH3Br , CH3Cl , CH3F CH3I is ………. How do their boiling points compare?A. The following is the order from lowest boiling point to highest based on the types of forces these compounds have: $\ce{CO2}$ - dispersion forces $\ce{CH3Br}$ - dispersion and dipole-dipole $\ce{CH3OH}$ - dispersion, dipole-dipole, and hydrogen bonding $\ce{RbF}$ - ionic Thus, the boiling point of isopropyl alcohol is lower than that of 1-chloropropane. CH3CL. The order of the distillates would be CH4, CH3Cl, CH2Cl2, CHCl3, and CCl4.Cl is larger than H and allows greater van der Waals contact. Give reason. Lv 7.

CH3I. Dies geschieht in Ihren Datenschutzeinstellungen. CH3Cl, CH4, CH3OH' and find homework help for other Science questions at eNotes Dear student Mr. Mayank; Dipole moment in CH3F is less than CH3Cl as bond length is shorter in CH3F Hence: CH3Cl > CH3F > CH3Br > CH3I Please feel free to … CH3BR. Based on molecular mass and dipole moment of the five compounds in the table below, which should have the highest boiling point? Chemistry I figured that CH3Cl would have stronger IM forces because Cl is able to pull on the carbon's electrons more than I is because Cl is much smaller than I, which would cause a greater dipole moment in CH3Cl … The molar masses of C2H6, CH3OH and CH3F are very similar. 1 decade ago.

Water has the highest boiling point because it has the greatest degree of hydrogen bonding and is the most polar, allowing for high intermolecular force levels. The decreasing order of bond length among alkyl halides (CH2I , CH2Br , CH3F , CH3Cl ) is in the order ………, Basic Concepts of Chemistry and Chemical Calculations. QuiteNewHere. Yahoo ist Teil von Verizon Media. In the second order: Even though F is more electronegative, CH3Cl has greater dipole moment because the bond length in this case is far longer than that in the case of CH3F since F is highly electronegative and it attracts the electron pair very strongly. In the comparison of RF vs RI boiling point, molecular weight is definitely in favor of higher boiling points for RI, at least for small molecules.
