Interpretation:
The products for each of the given reactions are to be predicted.
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 aldol reaction with two different carbonyl compounds is termed as a crossed aldol reaction.
In crossed aldol condensation, weak bases, like hydroxide, or an alkoxide are used in the protic solvent.
In a directed aldol reaction, a strong base, like LDA, is used in an aprotic solvent.
The Claisen condensation is the carbon-carbon bond formation reaction and is important for the preparation of
In Claisen condensation, the ester of one molecule is added to the carbonyl carbon of another molecule and the formation of
When one ester molecule has no alpha hydrogen, crossed Claisen condensation occurs.
