Identify the product ' X ' formed in the following reaction, Sodium ethoxide + Isopropyl chloride X+ Ethanol + Sodium Chloride

Options

  1. A1-Ethoxypropane
  2. B2-Ethoxypropane
  3. CPropene
  4. DPropane

Correct answer

C. Propene

Step-by-step solution

Sodium ethoxide ( CH₃CH₂ONa ) is a strong base and nucleophile, while isopropyl chloride ( CH₃CHClCH₃ ) is a secondary alkyl halide. This combination can lead to either substitution ( S_N2 ) or elimination ( E2 ) reactions. In an E2 elimination, the ethoxide ion acts as a base, abstracting a -hydrogen from the alkyl halide. The products are propene ( CH₂=CHCH₃ ), ethanol ( CH₃CH₂OH ), and sodium chloride ( NaCl ). The formation of ethanol is characteristic of E2 elimination when ethoxide is the base. A substitution
