In the subject of this post you have written alkanes and these are, I think alkenes.
what is the reagent used in allylic bromination of CH3CH2CH=CH2
NBS, just like in this example.
Hey I think you are wrong because in the third and fourth reaction from top you forgot allylic rearrangement
Good point! This should be updated to reflect the potential for allylic rearrangement.
Hey from where exactly are you getting the HBr
The dirty secret with this reaction is that it works best with slightly impure NBS, which contains HBr.
