Reactivity and Mechanistic Factors
Explore how factors like carbocation stability, nucleophile strength, solvent effects, and leaving group ability influence reaction pathways.
Why this shows up in the exam
Understanding these factors helps you predict which mechanism or product will dominate.
How NEET tests this
Practise it
These are real questions from past NEET papers that test this exact idea.
Consider the reaction, CH₃CH₂CH₂Br + NaCN → CH₃CH₂CH₂CN + NaBr This reaction will be the fastest in
Push further
More challenging22 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.
Consider the following statements: Assertion (A): The rate of SN2 reaction of CH3F is slower than CH3I. Reason (R): Fluoride ion is a better leaving group than iodide ion due to its higher electronegativity. Choose the correct option.
