Concept explainers
Interpretation:
The starting material, which gives the desired product through the given defined reaction on working backward, is to be deduced.
Concept introduction:
Acid catalyzed dehydration is a reaction in which the alcohol is converted into
Elimination reaction: A reaction in which two substituent groups present on adjacent positions are detached and a double bond is formed.
Nucleophilic substitution reaction: A reaction, in which one of the hydrogens of a hydrocarbon, or a functional group, is replaced by any nucleophile is called substitution reaction.
A nucleophile is a molecule or atom with negative charge or a lone pair of electrons.
The reaction in which the halide group is removed through elimination reaction to form the alkene is called dehydrohalogenation.
