Heating Copper with Isopropyl Alcohol

When vapours of isopropyl alcohol are passed over heated copper, the following reaction occurs:

2CH3CHOHCH3 (isopropyl alcohol) + heat → (Cu catalyst) → CH3COCH3 (acetone) + CH4 (methane)

Explanation:

Copper is a catalyst in this reaction, meaning that it speeds up the reaction without being consumed in the process. The reaction involves the dehydration of isopropyl alcohol to form acetone and methane.

Isopropyl alcohol has the following structural formula:

CH3CHOHCH3

Acetone has the following structural formula:

CH3COCH3

Methane has the following structural formula:

CH4

Therefore, the major product obtained when vapours of isopropyl alcohol are passed over heated copper is acetone (option D).
