Concept explainers
Interpretation:
The products that would be formed in the given reactions are to be identified.
Concept introduction:
Electrophiles are electron deficient species that have positive or partially positive charge. Lewis acids are electrophiles that accept electron pair.
Nucleophiles are electron rich species that have negative or partially negative charge. Lewis bases are nucleophiles that donate electron pair.
Free radical is an atom, molecule, or ion that has an unpaired electron, which makes it highly chemically reactive.
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 the addition of molecules.
An organic reaction in which conversion of an
An organic reaction in which the formation of an ester takes place from a ketone where peroxides or peroxyacids are used as oxidant is known as Baeyer-Villiger oxidation.
The organic reaction in which an electrophile replaces the atom attached to the
Diels-alder reaction is an organic reaction in which a diene and a dienophile react with each other in order to form a ring or bicyclic compounds. It is a single step reaction.
