What is Hunsdiecker reaction give an example?
It is an example of both a decarboxylation and a halogenation reaction as the product has one fewer carbon atoms than the starting material (lost as carbon dioxide) and a halogen atom is introduced its place….

Which of the following reactions is known as Hunsdiecker reaction?
The Hunsdiecker reaction (also referred to as the Borodin reaction or the Hunsdiecker-Borodin reaction) is an organic chemistry name reaction whereby carboxylic acid silver salts react to create an organic halide with a halogen.
How will you get alkyl halide Hunsidieker method?
The Hunsdiecker Reaction is the reaction of a silver carboxylate with a halogen to form an alkyl halide. The reaction involves a radical chain mechanism. The bromine reacts with the silver carboxylate (1) to give an unstable acyl hypobromite (2).
Which of the reactions are most common in alkyl halides?
Alkyl halides can undergo two major types of reactions – substitution and/or elimination. The substitution reaction is called a Nucleophilic Substitution reaction because the electrophilic alkyl halide forms a new bond with the nucleophile which substitutes for (replaces) the halogen at the alpha-carbon.
Which reagent Cannot be used to prepare an alkyl chloride from an alcohol?
NaCl cannot be used for the preparation of alkyl chlorides from alcohols.
What is are true about E1cB reaction?
The E1cB elimination reaction is a type of elimination reaction which occurs under basic conditions, where the hydrogen to be removed is relatively acidic, while the leaving group (such as -OH or -OR) is a relatively poor one.
Why do E1cB reactions occur?
The E1cB Reaction This reaction is generally utilized when a poor leaving group, such as an alcohol, is involved. This poor leaving group makes the direct E1 or E2 reactions difficult. This reaction is used later in a reaction called an aldol condensation.
Is called Simmons-Smith reagent?
Iodomethylzinc iodide, known as the Simmons–Smith reagent, is a carbenoid. In the Simmons–Smith method, diiodomethane reacts with a zinc–copper alloy to produce an intermediate I—CH2Zn—I compound.
