Concept explainers

Metallurgy could be defined as a technique by which metals can be extracted in their pure nature. Extractive metallurgy directs with the route of eradicating the valuable metals from ores and purifying the extracted metals to pure nature. In hydrometallu…

Question

Definition Definition Molecules that have multiple bonds between their carbon atoms. Alkenes are hydrocarbons with a double bond between two adjacent carbon atoms (R 2 C=CR 2 ), whereas alkynes are hydrocarbons with a triple bond between two adjacent carbon atoms R-C=C-R . These two groups are known as unsaturated hydrocarbons. They have fewer hydrogen atoms when compared with alkanes with same number of carbon atoms. The general molecular formula for an unsaturated hydrocarbon can be represented as C n H 2n +2 .

Chapter 20.2, Problem 3RQ

Interpretation Introduction

Interpretation: The similarity between halogenation and hydrogenation reaction is to be written.

Concept Introduction: In halogenation and hydrogenation reaction, halogen gas and hydrogen gas are added to unsaturated hydrocarbons respectively.

Expert Solution & Answer

Answer to Problem 3RQ

Both hydrogenation and halogenation reactions are addition reactions and the products formed in both reactions are saturated.

Explanation of Solution

In hydrogenation reaction, hydrogen gas is added to unsaturated alkenes or alkynes in the presence of nickel or palladium as catalyst to form saturated alkanes. In halogenation reaction, halogen gases(bromine, chlorine or iodine) are added to unsaturated alkenes or alkynes to form various different haloalkanes as products. All these products are saturated hydrocarbons.
