## Complete Guide: Organic Chemistry ### Complete Alkane in one page - **Hydrogenation**: - Alkenes + H2 → Alkanes - Alkynes + H2 Ni/Pt/Pd → Alkanes - **From Alkyl Halides**: - R-X Zn/H+ → R-H - R-O-R I > Br > Cl ≠ F - **Wurtz Reaction**: - R-X + Na → R-R + 2X - Dry ether...
## Complete Guide: Organic Chemistry ### Complete Alkane in one page - **Hydrogenation**: - Alkenes + H2 → Alkanes - Alkynes + H2 Ni/Pt/Pd → Alkanes - **From Alkyl Halides**: - R-X Zn/H+ → R-H - R-O-R I > Br > Cl ≠ F - **Wurtz Reaction**: - R-X + Na → R-R + 2X - Dry ether - R-O-R I > Br > Cl > F - **1° 2° 3° RX**: - <Intramol> Intermol. - **Decarboxylation**: - R-COOH + NaOH+CaO → R-H - OR R-COONa Soda lime → R-H - **Kolbe's electrolysis**: - electro. R-R - R-COONa - cathode - H2 (g) - Anode - CO2 (g) - **Halogenation**: - (R-X) + X2 → R-X + H-X - R-O-R-F2 > Cl2 > BY2 > I2 - High more reactive less reactive - less selective more selective - **Chemical Properties**: - For iodination R-H + I2 → R-I + HI - **Isomerisation**: - Ahhy AlCl3 - HCl - **Aromatisation**: - Cr2O3 or V2O5 - 773 k, 10-20 atm - **Controlled Oxidation**: - 2CH4 + 02 CU/523k → 2CH3OH (IH-OH) - CH4 + O2 M0203 → HCHO + H₂O (2H-OH) - 2CH3-CH3 + 302 → 2CH3COOH + 2H20 (3H-OH) - KMnO4, OH → (3H-OH) - **Combustion**: - CxHy+ (x+1) 02 → CO2 + H2O (exo) - **Reaction with steam**: - CH4 + H2O → Co + 3H2 - Ni - Δ - water gas. - **Pyrolysis (cracking)**: - C6H14 → CCH12 + H2 - 773 k - C4H8+ C2H6 - C3H6 + C2H4 + CH4 - **Physical Properties**: - B.PM.W x 1 - Branching - solubility - like dissolve like - (Polar in Polar) - (Non polar in non polar) ### Complete Alkynes in one page - **From Carbides**: - CaCO2 → CaO + CO2 coke - CaC2 → Ca(OH)2 + CH=CH Acetylene - Mg2C3 → Mg(OH)2 + CH3-C≡CH propyne - **From Dehydrohalogenation**: - @alc-KOH → -CEC- - **Acidic Nature**: - Terminal alkynes are acidic in nature - NaHCO₃ + R-CEC-H → R-C=CNa + H₂ - NaH + R-CEC-H → R-C=CNO + H2 - NaOH + R-CECNO → R-CECNO + NH3 - **Addition Reactions**: - **Hydrogenation**: - H2 + Pd →
