Question: What is the expected major product when 1-chloropropane reacts with potassium tert-butoxide?

Options:

Correct Answer: Propene

Solution:

The reaction of 1-chloropropane with potassium tert-butoxide favors elimination, leading to the formation of propene as the major product.

What is the expected major product when 1-chloropropane reacts with potassium tert-butoxide?

What is the expected major product when 1-chloropropane reacts with potassium tert-butoxide?

Step 1: Identify the reactants. We have 1-chloropropane, which is a primary alkyl halide, and potassium tert-butoxide, which is a strong base.
Step 2: Understand the type of reaction. Potassium tert-butoxide is a strong base that promotes elimination reactions rather than substitution reactions.
Step 3: Determine the elimination mechanism. Since 1-chloropropane is a primary halide, the elimination will likely follow the E2 mechanism.
Step 4: Identify the elimination product. In the E2 reaction, the base (potassium tert-butoxide) removes a hydrogen atom from the adjacent carbon, leading to the formation of a double bond.
Step 5: Draw the product. Removing a hydrogen from the second carbon of 1-chloropropane and eliminating the chlorine atom results in the formation of propene.
Step 6: Conclude the major product. The major product of the reaction is propene.
