Answer: 3-Chloro-pentane will undergo dehydrohalogenation to give 2-pentene .

Explanation:

On dehydrohalogenation ,the chlorine atom present on the central [tex]C^3[/tex] with one hydrogen atom either from [tex]C^2[/tex] carbon atom or from [tex]C^4[/tex] carbon atom will get removed in form of HCL from the molecule of 3 chloro- pentane. Pent-2-ene will be obtained as single pure product in the end. As shown in the image attached.

Answer:

3-chloropentane.

Explanation:

Hello, in this case, an elimination chemical reaction must be considered since the reactant is an alkyl halide, in such a way, we must conserve the main 5-carbon chain and look for the suitable position of the to-eliminate halogen which is chlorine. Now, on the attached picture, you will see that such halide is 3-chloropentane as long as its dehydrohalogenation is carried out in a strong basic media provided by potassium hydroxide (KOH) and using ethanol as a solvent to allow the 2-pentene to be yielded in addition to the side products such as hydrochloric acid or potassium chloride.

Best regards.
