Formation Reactions

Forming Alkanes
Hydrog­enation of Alkene (Addition RX)
 
H2 + Alkene = Alkane
Forming Alkenes
Dehydr­ation of Alcohol
 
Alcohol (H2SO4) = Alkene + H2O
 
Substi­tution RX + Elimin­ation RX
 
Alkane + Halogen = Alkyl Halide + (HCL)
 
Alkyl Halide + OH- = Alkene + (Cl) + H2O
 

Formation Reactions

Forming Alcohols
Alkene + H2O =(H2SO) Alcohol
 
HYDROG­ENATION RX
 
Aldehyde (reducing agent) = 1 alcohol
 
Keytone (reducing agent) = 2 alcohol
Forming Ethers
CONDEN­SATION RX
 
Alcohol + Alcohol (H2SO4) = Ether + H2O
Forming Aldehy­des
OXIDATION RX
 
1 Alcohol + [O] = Aldehyde + H2O
Forming Keytones
2 Alcohol + [O] = Keytone + H2O
Forming Carboxylic Acids
Aldehyde + [O] = Carboxylic Acid
Forming Esters (ester­fic­ation)
Carboxylic Acid + Alcohol (H2SO4) = Ester + H2O
Forming Amines
Alkyl Halide + Ammonia = Amine + HI
Forming Amides
Carboxylic Acid + Ammonia (H2SO4) = Amide + H2O
 

Other Reactions

Comb­ustion RX
Complete : __ + O2 = CO2 + H2O
 
Inco­mp: __ + O2 = CO2 + H2O + CO + C
Alka­nes
SUBSTI­TUTION RX
Alkenes & Alkynes
ADDITION RX
 
Haloge­nat­ion... Hydrog­ena­tion... Hydroh­alo­gen­ati­on... Hydration
Esters
HYDROLYSIS (soapo­nif­ica­tion)
 
Ester + NaOH = Sodium Carbox­ylate + Alcohol
