Questions & Step-by-Step Solutions
What is the major product of the reaction between 1-butyne and H2 in the presence of a catalyst?
Step 1: Identify the starting material, which is 1-butyne. It is an alkyne with the formula C4H6.
Step 2: Understand that hydrogenation is a reaction where hydrogen (H2) is added to a compound.
Step 3: Recognize that a catalyst is used to speed up the reaction. Common catalysts for hydrogenation include palladium (Pd), platinum (Pt), or nickel (Ni).
Step 4: When 1-butyne reacts with H2 in the presence of a catalyst, the triple bond between carbon atoms in 1-butyne is broken.
Step 5: As a result of breaking the triple bond, two hydrogen atoms are added to the molecule.
Step 6: The product formed after the reaction is butane, which is an alkane with the formula C4H10.
Step 7: Conclude that butane is the major product of the hydrogenation of 1-butyne.
