(a)
Interpretation:
For each given E2 reactions the used alkyl halide are needed to be drawn.
Concept introduction:
In an elimination reaction,
The product of the elimination reaction is depends upon the β-positions of alkyl halide. If the β-positions are identical and the products formed are also identical. If the β-positions are different and the products formed are also different. This means the double bond can form in two different regions, so it will give different alkene products.
To draw: the alkyl halide used for given E2 reactions.
(b)
Interpretation:
For each given E2 reactions the used alkyl halide are needed to be drawn.
Concept introduction:
In an elimination reaction, alkenes are formed when alkyl halides are treated with bases via eliminating one β-proton and one α-halo group of the alkyl halide. The double bond is located between α,β-carbons.
The product of the elimination reaction is depends upon the β-positions of alkyl halide. If the β-positions are identical and the products formed are also identical. If the β-positions are different and the products formed are also different. This means the double bond can form in two different regions, so it will give different alkene products.
To draw: the alkyl halide used for given E2 reactions.
