The first reaction involves the conversion of ethene (C2H4) to ethanol (C2H5OH), which is an addition reaction that adds a hydroxyl group (-OH) to the carbon-carbon double bond in ethene.
The second reaction involves the conversion of ethanol (C2H5OH) to acetaldehyde (CH3-COH), which is an oxidation reaction that removes hydrogen atoms from ethanol to form the aldehyde group (-CHO) in acetaldehyde.
The given reaction sequence is:
C2H4 -> C2H5OH -> CH3-COH
