Question 54

Which one of the following reagents is not suitable for the elimination reaction?

Elimination requires a strong base to remove a $$\beta$$-hydrogen and form an alkene.

$$NaOEt/EtOH$$ and $$NaOH$$ (with heat or alcohol) act as strong bases, so they favor elimination.

$$NaI$$ provides $$I^-$$, which is a good nucleophile but a weak base. Hence, it undergoes substitution instead of elimination.

Therefore, $$NaI$$ is not suitable for the reaction.
