E1 vs E2

E1 vs E2 - organic chemistry study tip. Mnemonic: E2: Everything (H and LG) leaves at the same time. E2 requires anti-periplanar geometry (H and leaving group 180° apart). E1 makes the more stable carbocation first. Bulky bases favor elimination over substitu...

Mnemonic

E2: Everything (H and LG) leaves at the same time

Tip

E2 requires anti-periplanar geometry (H and leaving group 180° apart). E1 makes the more stable carbocation first. Bulky bases favor elimination over substitution.

SN1 vs SN2

SN1 vs SN2 - organic chemistry study tip. Mnemonic: SN2: Strong Nucleophile, Secondary or primary. SN2 works best with methyl and 1° substrates (steric hindrance matters). SN1 works best with 3° (carbocation stability matters). 2° can go either way - look at...

Zaitsev vs Hofmann Products

Zaitsev vs Hofmann Products - organic chemistry study tip. Mnemonic: Zaitsev = "Z" for "Ze more substituted" alkene. Zaitsev (most substituted alkene) is favored with small bases. Hofmann (less substituted) is favored with bulky bases like KOtBu or with poor...

Markovnikov's Rule

Markovnikov's Rule - organic chemistry study tip. Mnemonic: Rich get richer: H goes to C with more H's. In electrophilic addition, the electrophile (usually H⁺) adds to the carbon with MORE hydrogens, forming the more stable carbocation on the more substitute...

Anti-Markovnikov Addition

Anti-Markovnikov Addition - organic chemistry study tip. Mnemonic: Peroxides promote anti pattern. HBr + peroxides (ROOR) = anti-Markovnikov via radical mechanism. Only works with HBr (not HCl or HI). Hydroboration-oxidation also gives anti-Markovnikov alcoho...

Carbocation Stability

Carbocation Stability - organic chemistry study tip. Mnemonic: 3° > 2° > 1° > methyl (like a countdown). More substituted carbocations are more stable due to hyperconjugation and inductive effects. Watch for rearrangements (hydride and methyl shifts) to form...

Nucleophilicity vs Basicity

Nucleophilicity vs Basicity - organic chemistry study tip. Nucleophilicity = how fast it attacks carbon (kinetic, steric matters). Basicity = equilibrium with proton (thermodynamic, pKa matters). Good nucleophiles aren't always strong bases (e.g., I⁻, RS⁻).
