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 goal of an airbag is to slow the passenger's forward motion as evenly as possible in a fraction of a second. There are three parts to an airbag that help to accomplish this feat: 1  The bag itself is made of a thin, nylon fabric, which is folded into the steering wheel or dashboard or, more recently, the seat or door.2  The sensor is the device that tells the bag to inflate.he inflation system uses a solid propellant and an igniter. They needed a way to set off a chemical reaction that would produce the nitrogen that would inflate the bag. Small solid-propellant inflators came to the rescue in the 1970s.
