I know that CH3CL and CH3BR are released even without boiling, and are most predominant . CH3I comes in third.
The answer is CH3F.

For a series of compounds with similar structure boiling point is in order of molecular weight (size) so the heaviest CH3I has the highest B.Pt, CH3F the lowest.

Boiling point decrease as you go down the group. So CH3F has the lowest Boiling point and CH3I has the highest Boiling point.

CH3F I would say because it has the most polar/the strongest bond and therefore would take more energy in the form of heat to break.
