Concept explainers
Interpretation:
The products of the given acid–base reactions are to be predicted and, in each case, the stronger acid, the stronger base, the weaker acid, and the weaker base are to be labeled.
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.
Addition reaction: It is the reaction in which unsaturated bonds are converted to saturated molecules by addition of molecules.
Sodium amide is a strong base that helps in the removal of terminal hydrogen of
