a)
Interpretation:
The actual product has to be identified.
Concept introduction:
Elimination reaction:An elimination reaction is removal of two substituents in a molecule and forms
E1 elimination:
E2 elimination:Alkyl halide forms an alkene from the abstraction of the proton from the β-carbon atom followed by elimination of the bromine in a single step.
b)
Interpretation:
The actual product has to be identified.
Concept introduction:
Elimination reaction:An elimination reaction is removal of two substituents in a molecule and forms alkene. An elimination reaction is one or two-step process which based on the mechanism when two substituents removed from the molecule in single step is called E2 reaction. When two substituents are removed from the molecule in two steps is called E1 reaction.
E1 elimination: Alkyl halide forms carbocation by the removal of bromine followed by the abstraction of the proton from the β-carbon atom in two steps which leads to the product as an alkene
E2 elimination:Alkyl halide forms an alkene from the abstraction of the proton from the β-carbon atom followed by elimination of the bromine in a single step.

She placed these two compounds through various scientific tests. She discovered that these compounds have the same molecular formula, CSHSO. When treated with 2,4-dinitrophenylhydrazine, all of these compounds produce brightly coloured precipitate, and both are reduced to an organic compound with the molecular formula C§H100. However, compound K can be easily oxidized by chromic acid to formed compound N and vice versa for compound L. Furthermore, when both compounds react with Fehling's solutions, they produce negative results. However, only compound K forms a silver mirror when it reacts with Tollen's reagent, and compound L does not. Identify the possible structural formulae for compounds K, L, and N by ignoring their position isomerism. Indicate the formation of compound N from compound K.
