Using the aldehyde below, list the characteristic peaks you would expect to see in a ${?}^{1}H$ NMR$.(2)$

Describe which ${?}^{1}H$ NMR peaks do you predict would be the MOST indicative of the reductive amination product below? $(2)$

Which ${?}^1$ HNMR peaks do you expect to not be present in the product that were present in the starting material? $(2)$

Focus on desired amine product and compare it to the alcohol byproduct. Do you think the highlighted hydrogens would have the same or different chemical shift? Which will be more "downfield"? Why? $(2)$
