Question

Quizplus · Accepted Answer

When hydrogen is added to 1-pentene in the presence of a platinum catalyst, the product is 1-pentane. The addition of hydrogen to an alkene (such as 1-pentene) is called hydrogenation, which results in the conversion of the double bond to a single bond. If the reaction is conducted under harsher conditions (higher temperatures and pressures), it is possible for over-hydrogenation to occur, resulting in the formation of an alkyne (such as 1-pentyne). However, under normal hydrogenation conditions, 1-pentyne is not the product.
