Wood · Answer 1

Propane

Step-by-step explanation:

One way to reduce an alkyl halide is the Grignard reaction.

You react 2-bromopropane with magnesium in dry ether to form isopropylmagnesium bromide.

In the second step, the strongly basic Grignard reagent abstracts a proton from water and is converted to propane.

Cohen Cross · Answer 2

To reduce a haloalkane, it has to be eliminated first. This is because 2 bromopropanes are a saturated compound that can not be reduced by a saturated compound. Dehydrohalogenation of the haloalkanes into the form of propene and hydrogen bromide can lead to the elimination. The propene is then reduced to propane.
