Which of the following compounds will NOT produce propene by reaction with \( \text{HBr} \) followed by elimination or direct only elimination reaction?

  1. \( \text{H}_2\text{C}=\text{CH}_2 \)
  2. \( \text{H}_3\text{C}-\text{CH}_2-\text{CH}_2\text{OH} \)
  3. \( \text{CH}_3-\text{CH}=\text{CH}_2 \)
  4. \( \text{H}_3\text{C}-\text{CH}_2-\text{CH}_2\text{Br} \)

Correct answer · Option 1

\( \text{H}_2\text{C}=\text{CH}_2 \)

Explanation

Ethene (\( \text{H}_2\text{C}=\text{CH}_2 \)) has only 2 carbons, so it cannot produce a 3-carbon compound like propene.
