ORDER AND FACTS OF ORGANIC CHEMISTRY

πŸ”»1. RCOCl > RCOOCOR > RCOOR > RCONH2 Nucleophilic substitution reaction.

πŸ”»2. HI > HBr > HCl > RCOOH > C6H5OH > H2O > CH CH > NH3 (Acidic nature).

πŸ”»3. CCl3CHO > HCHO > CH3CHO > CH3COCH3 Nucleophilic addition reaction.

πŸ”»4. CH2 = CH2 > CH CH > C6H6 Electrophilic addition reaction.

πŸ”»5. (CH3)2C = C(CH3)2 > CH3 – CH = C -(CH3)2 > CH3 – CH = CH – CH3 > CH3 – CH = CH2 (Stability)

πŸ”»6. NI3 > NBr3 > NCl3 > NF3 (Basic strength)

πŸ”»7. Br2 > Cl2 > I2 (Selectivity for halogenation)

πŸ”»8. Halogenation of alkenes by cyclic halonium state, so anti attack takes place.

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

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

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