Saytzeff product will be obtained maximum, when X is :
Correct answer: A. -I
- A. -I
- B. -Cl
- C. -Br
- D. -F
Explanation
Greater the tendency of the leaving group, greater is the formation of Saytzeff's product. The order of decreasing tendency of leaving group is I− > Br− > Cl− > F−. In other words, better the leaving group, maximum is the percentage of Saytzeff's product.

About Alkyl Halides
Alkyl halides are named and related to their carbon-halogen structure, polarity and reactivity. The key reactions are nucleophilic substitution by SN1 and SN2 mechanisms and elimination by E1 and E2 mechanisms, including how substrate structure, nucleophile, base, solvent and temperature influence substitution versus elimination.
