Matching catalyst for Haber process and product of alkene hydrogenation

Steps:

• Identify Haber process: N₂ + 3H₂ ⇌ 2NH₃, catalyzed by iron.
• Identify alkene hydrogenation: Alkene + H₂ → alkane, catalyzed by nickel.
• Determine row format: First word as Haber catalyst, second as alkene product.
• Match to choices: Iron for Haber, alkane as product.

Why A is correct:

• Haber process uses iron catalyst (promotes N≡N bond breaking); alkene + H₂ yields alkane via addition across C=C bond.

Why the others are wrong:

• B: Nickel catalyzes hydrogenation, not Haber process.
• C: Nickel is alkene hydrogenation catalyst, but Haber requires iron.
• D: Hydrogenation product is alkane, not alcohol.

Final answer: A
