Chapter 11.5, Problem 11.10Q

Interpretation Introduction

Interpretation:

Balanced equation for the hydrogenation of 1-butene and cis-2-butene has to be written.

Concept Introduction:

Addition of hydrogen molecule to an unsaturated bond present in hydrocarbon is known as hydrogenation.  During hydrogenation, the unsaturated bond present is broken and a carbon‑hydrogen bond is formed.  Hydrogenation can be accomplished by use of metal catalyst such as platinum, nickel, or palladium.  If an alkene contains one double bond, one molecules of hydrogen is required for hydrogenation.  If it contains two double bonds, then two molecules of hydrogen is required for hydrogenation and so on.

Balanced equation is the one where the atoms of the same kind are equal on both sides of the chemical equation.
