Predict a correct sequence of reactants required to complete the following transformation in which propanal is the only carbon-containing product.

Question

Quizplus · Accepted Answer

The transformation involves the reduction of propanal to propanol, followed by dehydration to form propene, and then catalytic hydrogenation to form propanal.

The correct sequence of reactants is:
1) I - NaBH4 as a reducing agent for propanal to propanol
2) IV - Acid catalyst (such as H2SO4) for dehydration of propanol to propene
3) VI - Catalyst (such as Pd/C) for the selective hydrogenation of propene to propanal
4) V - Hydrogen gas as the source of hydrogen for the hydrogenation reaction
5) II - Distilled water to remove any remaining acid from the previous steps

Therefore, the correct sequence of reactants is D) 1) I; 2) IV; 3) VI; 4) V; 5) II.
