CH2Cl2: 40°C
CH2Br2: 98°C
CH2I2: 182°C
Which of the following statements is correct for this set of compounds and supported by the data given? Select as many as applicable however points will be deducted for incorrect choices.
Select one or more:
1) The dominant effect behind this trend is the strength of dipole/dipole forces
2) CH2I2 is the most polarizable molecule of the four
3) The molecule with the strongest intermolecular forces is CH2F2
4) The C-I bond is the strongest covalent bond among the four molecules
5) The dominant effect behind this trend is the strength of dispersion forces
6) CH2F2 is the most polarizable molecule of the four
