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.

The bag's internal pressure, when fully inflated is about 10 to 30  kPa, which is comparatively low but sufficient to safeguard the  driver if dashed against it. The driversâ¦ thrust on the air-bag  pushes gas to escape through two large outlet holes in the rear of  the bag to further cushion the impact.
