E2 bimolecular elimination (Rate = k[RX][B⁻]; concerted anti-periplanar β-elimination (ideal geometry))
jee-mainjee-advancedneet-ug
Rate = k[RX][B⁻]; concerted anti-periplanar β-elimination (ideal geometry)
What each symbol means
| Symbol | What it stands for |
|---|---|
| k | Rate constant |
| RX | Substrate with β-H |
| B⁻ | Strong base |
When to use this
Strong base (often HO⁻, RO⁻, NH₂⁻); typically polar solvent; good LG. Bulky bases favor Hofmann regioselectivity.
