Answer 2

Conversion of CH3CHO to X1

To convert CH3CHO to X1, the reaction requires the presence of hydrogen gas (H2) and a catalyst such as nickel (Ni) at a certain temperature (t). This reaction is known as hydrogenation, where the aldehyde group (-CHO) is reduced to an alcohol group (-CH2OH).

Conversion of X1 to X2

To convert X1 to X2, the reaction involves the addition of hydrogen bromide (HBr). This reaction is known as hydrobromination, where the hydrogen bromide adds across the double bond of the alcohol group, resulting in the formation of an alkyl bromide.

Conversion of X2 to ethylene

To convert X2 to ethylene, the reaction requires the elimination of hydrogen bromide (HBr) from the alkyl bromide. This reaction is known as dehydrohalogenation, where the alkyl bromide loses a molecule of HBr to form ethylene.

Conversion of ethylene to CH3CHO

To convert ethylene back to CH3CHO, the reaction involves the addition of silver oxide (Ag2O) and ammonia (NH3). This reaction is known as the Wacker process, where ethylene is oxidized to acetaldehyde.

Conversion of CH3CHO to X3
