Which of molecular solid would have the lowest boiling point?

Among molecular solids, substances with weaker intermolecular forces typically have lower boiling points. For example, simple molecular solids like iodine (I₂) or dry ice (solid carbon dioxide, CO₂) exhibit relatively low boiling points compared to those with stronger hydrogen bonding or dipole-dipole interactions. Therefore, a molecular solid like carbon dioxide would generally have a lower boiling point than more complex or polar molecular solids.
