Final answer:
The reagents capable of converting 1-propoxypropane into 1-bromopropane are hydrobromic acid (HBr) and phosphorus tribromide (PBr3). Bromine (Br2) and sodium bromide (NaBr) are not suitable for this reaction.
Step-by-step explanation:
The conversion of 1-propoxypropane into 1-bromopropane involves the substitution of the propoxy group with a bromine atom. The reagents that can facilitate this substitution are HBr (hydrobromic acid) and PBr3 (phosphorus tribromide). Both of these reagents are capable of reacting with ethers to produce alkyl halides. Hydrobromic acid may require an additional catalyst, such as sulfuric acid, to proceed, whereas phosphorus tribromide can directly convert an ether into the corresponding alkyl bromide. Br2 (bromine) and NaBr (sodium bromide) are not effective in this conversion as they do not readily substitute alkoxides with halides. Therefore, the correct answers are a) HBr and b) PBr3.
