Organic: Haloalkanes and Haloarenes

Question:

What is the correct order of reactivity of haloalkanes towards β-elimination reactions?

Options:

3°>2°>1°

3°>1°>2°

1°>2°>3°

1°>3°>2°

Correct Answer:

3°>2°>1°

Explanation:

The haloalkanes which will form more stable (highly substituted) alkenes are the ones that will react the fastest. Since tertiary alkyl halides will form the most stable alkenes, they are the most reactive.
