The answers provided on Chegg are either wrong or not whats needed. The extra infomration provided is from the textbook being used, I'm not sure if its helpful. From my understanding the answer should be in numbers being compared to propane. I'm not sure if this infomration is correct but mechanism should be SN? Please dont copy and paste from other chegg answers as they are wrong. show work and provide computer generated answers such as using notes app to answer and write/ draw clearly. This is for an organic chemistry course and I really need help.

Bromination of 1-bromoprapane produces dibromopropane isamers ratio: (1) What are the relative reactivities of hydrogens on each of the three carbons toward bromine atoms. (2) Campare these reactivities with those from propane and explain the differences. Extra info: should be SN mechanism Relative reactivities of various alkane CHCH bonds in halogenations can be estimated via factoring art statistical contributians. They are roughly castant under identical conditions and adhere the order: CHH
