ORDER AND FACTS OF ORGANIC CHEMISTRY

🔻1. RCOCl > RCOOCOR > RCOOR > RCONH2 Nucleophilic substitution reaction.

🔻2. HI > HBr > HCl > RCOOH > C6H5OH > H2O > CH CH > NH3 (Acidic nature).

🔻3. CCl3CHO > HCHO > CH3CHO > CH3COCH3 Nucleophilic addition reaction.

🔻4. CH2 = CH2 > CH CH > C6H6 Electrophilic addition reaction.

🔻5. (CH3)2C = C(CH3)2 > CH3 – CH = C -(CH3)2 > CH3 – CH = CH – CH3 > CH3 – CH = CH2 (Stability)

🔻6. NI3 > NBr3 > NCl3 > NF3 (Basic strength)

🔻7. Br2 > Cl2 > I2 (Selectivity for halogenation)

🔻8. Halogenation of alkenes by cyclic halonium state, so anti attack takes place.

🔻9.Hydroboration followed by oxidation is always anti markownikoff’s addition due to steric effect.

🔻10. Oximercuration – demercuration is m.K. addition of water because some carbocation character in cyclic mercurium state.

🔻11CHCl3 in the presence of strong bases forms biradical : CCl2 which undergo addition with double or triple bonds.
