Alkyl Halide Reactions. The functional group of alkyl halides is a carbon-halogen bond, the common halogens being fluorine, chlorine, bromine and iodine. With the exception of iodine, these halogens have electronegativities significantly greater than carbon.
Its been said that most car companies make it so where airbags deploy based on the impact. It is said that the airbag will not deploy until the impact generates 7 G's of force. For most vehicles that speed is equivalent to hitting an object at 12 mph or hitting another vehicle at 25 to 30 mph. It is dependent upon the impact of the crash.

Because air bag sensors measure deceleration, vehicle speed and damage are not good indicators of whether or not an air bag should have deployed, NHTSA said on its website. Occasionally, air bags can deploy due to the vehicle's undercarriage violently striking a low object protruding above the roadway surface.
