Actually what i meant was why why does cl2 have a higher boiling point, = /

Cl2 has a higher boiling point because it has a larger electron cloud. The outer electrons of the Cl2 are further away from the nucleus than F2's outer electrons, making them more susceptible to participating in London Dispersion Forces. This increases the attraction one Cl2 molecule has for another and requires additional energy (higher boiling point) to separate the molecules so that the liquid becomes a gas.

Cl2 has the higher boiling point because Cl has a larger electron cloud making it easier for an electron to stray far enough from the nucleus to create a dipole moment when bonded with another Cl2. Because of this, the bonding is stronger and will therefore have a higher boiling point.

You have just noted one of the characteristics of elements withing a group on the periodic table. Their melting points increase as you go down the group.

The increase in melting point is credited to the increase in mass of the atoms. This increase in mass causes a slight increase in the attractive forces between the atoms. The more attraction between the atoms--the higher the melting point.

because the intermolecular force among the Cl2 molecules is bigger than intermocelular force amog F2.........and Cl2 is bigger than F2, this influence too
