Have antifreeze leaking in front of car by the front wheels. Smells like antifreeze burning. why?

I am unsure what question your asking....If you are smelling burning anit-freeze it is because it is leaking either onto your engine, exhaust, etc....Check your hoses and around/near your water pump, thermostat and the inlet and outlet hoses on your radiator and overflow tank...look for wetness, discoloration around where hoses connect and the hose clamps. When do you start to smell anit-freeze? Is it right away after car warms up or does it take awhile?

The anti-freeze smells like it burning because it is coming in contact with your brake pads (will contaminate pads and reduce life and increase stopping distance, exhaust system (most likely cause of burning smell), or some other hot spot on the the engine.

You should resolve this as it will cause over heating as the system can not properly pressurize and reduced coolant level.
