Which of the following has strongest intermolecular forces of attraction ?
- Hydrogen (H2)
- B. Chlorine (Cl2)
- lodine (I2)
- Methane (CH4).
Explanation
According to most sources, Iodine (I2) has the strongest intermolecular forces of attraction
Iodine (I2):
Due to its large size and high number of electrons,
Iodine experiences the strongest London dispersion forces,
Which are the only type of intermolecular force present in nonpolar molecules like I2.
These forces are relatively weak compared to other types of intermolecular forces,
But in the case of large molecules like iodine, they become significant enough to result in a high boiling point.
