Khalid is learning about the preparation of alkanes by the reduction of alkyl halides. He uses 2-bromobutane (C4H9Br) and reduces it. What alkane is formed?

Structural isomers have the same:

Nora is studying the properties of alkanes. She knows that alkanes are generally unreactive but undergo combustion and halogenation. What type of reaction is halogenation?
