Question

What halide would undergo dehydrohalogenation to give 2-pentene as a pure product?

Answer 1

CH3-CH=CH-CH2-CH3 <--------CH3-CH2-CHCl-CH2_CH3
3-Cl-pentane , 3-Hal-pentane

Answer 2

The correct answer is 3-Chloropentane.

Step-by-step explanation:

Dehydrohalogenation refers to a chemical reaction, which includes elimination of a hydrogen halide from a substrate. The reaction is generally related to the production of alkenes, however, it has various uses. Conventionally, the alkyl halides are the substrates for dehydrohalogenations. The alkyl halide must possess the tendency to produce an alkene, therefore, benzyl and methyl halides are not the ideal substrates.
