Chlorine has the lowest boiling point as compared to other two (bromine and iodine) because Br and I is larger than Cl, therefore Br2 AND I2 has stronger intermolecular foces (Van der Waals) compared to Cl2. Among Br2 and I2 , Bromine has lower boiling point as compared to iodine ( same reason)

Hope , this helped you.
