Question

chlorination of alkanes is an
exothermic reaction, yet it requires
high temperature or
expose of uv light? why?​

Answer 1

Answer:

because a high temperature makes the molecule move more rapidly and have more energetic collisions it also makes the bond vibrate with greater amplitude so that the pound atoms are almost falling away from each other so the high-temperature promotes the initial step and UV light contains sufficient energy to break the the week and nonpolar Karan Karan bond but it has a fish in sufficient energy to break the stronger c-h bond this Karan Karan cravers leads to the formation of the two highly reactive chlorine free radicals does the high temperature and UV light promotes the initiation step in the chlorine chlorination of alkanes
