Elimination Reactions (E1 and E2) and Saytzeff's Rule
Learn about β-elimination, E1 and E2 mechanisms, factors affecting elimination, and the application of Saytzeff's (Zaitsev's) rule.
Why this shows up in the exam
You may be asked to distinguish between substitution and elimination and predict major products.
How NEET tests this
Practise it
These are real questions from past NEET papers that test this exact idea.
Reaction of t-butyl bromide with sodium methoxide produces
Push further
More challenging4 harder questions built from the past papers above — a step up in difficulty, with distractors designed so you can't get there by elimination. Written and checked by our reviewers, not from a real paper.
When 2-bromo-2-methylpropane reacts with potassium ethoxide in ethanol, the major organic product formed is:
