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.

Serious or even fatal injuries can occur when someone is very close to, or in direct contact with an air bag module when the air bag deploys, NHTSA said. With recent emphasis on preventing potential airbag injuries, and with onboard computers deciding to deploy or not to deploy, its perhaps not surprising that airbags don't deploy in every collision, even in ones where occupants think they should have.
