Concept explainers
Interpretation:
The mechanism for the addition of sulfuric acid to ethene for the production of ethanol is to be explained.
Concept Introduction:
Substitution reaction: A reaction in which one of the hydrogen atoms of a hydrocarbon or a
Elimination reaction: A reaction in which two substituent groups are detached and a double bond is formed is called elimination reaction.
Nucleophilic substitution reaction: A reaction in which one of the hydrogen atoms of a hydrocarbon or a functional group is substituted with any nucleophile is called nucleophilic substitution reaction.
Addition reaction: A reaction in which two or more unsaturated compounds react to form a product is called addition reaction.
