Question

What are addition reactions? How are addition reactions of ethene different from ethyne?

Answer 1

The reactions in which the molecules of the attacking reagent add across the double or triple bond of an unsaturated hydrocarbon to form saturated compounds are known as addition reactions. The addition reactions in ethene are completed in a single stage, while those in ethyne are completed in two stages. First, ethene is formed from ethyne followed by the formation of ethane.
