Defining the effect of CO2 as 1 GWP (Green House Potential) (On a 100 years base), we have

Effect of CO2 is 1 GWP
Effect of CH4 is about 20 GWP
Effect of N2O is about 300 GWP.

I don't know about the Chlorinated compounds, but it is high

I found some more numbers on wikipedia https://en.wikipedia.org/wiki/Global-warming_potential

Again, on a 100 years base

Effect of CO2 is 1 GWP
Effect of CH4 is about 25 GWP
Effect of N2O is about 300 GWP
Effect of CFC-11 is about 5300
Effect of HFC-23 is about 15000
