Question

Which of the following compounds does not follow Markovnikov's law?

• A. \( \text{CH}_3\text{CH}_2\text{CH}_3 \)
• B. \( \text{CH}_3\text{CHCl}_2 \)
• C. \( \text{CH}_3\text{CH}_2\text{C} = \text{CH}_2 \)
• D. None

Hint:

Markovnikov's law is followed in most alkene additions, but exceptions occur due to factors like stability of carbocation intermediates.

Answer 1

The Correct Option is C

Markovnikov's rule states that in the addition of HX to an alkene, the hydrogen atom adds to the carbon with the greater number of hydrogen atoms. The exception is the compound \( \text{CH}_3\text{CH}_2\text{C} = \text{CH}_2 \), which does not follow this rule.

Step 2: Conclusion.
Thus, the correct answer is \( \text{CH}_3\text{CH}_2\text{C} = \text{CH}_2 \).
