What is a unsaturated hydrocarbon
Hydrocarbon with at least one carbon carbon (double or triple) bond
Haloalkane functional group
C-X
(where X is Br,I,Cl,F)
Fluro, Bromo, Iodo, chloro
Amine functional group
R-NH2 (single bonds)
-amine
Amide functional group
C=ONH2
-amide
Alcohol functional group
OH
-ol
Aldehyde functional group
C=O (on a terminal carbon)
FOR SEMI STRUCTURAL SHOW THE FUNCTIONAL GROUP AS CHO RATHER THAN COH
-anal
Ketone functional group
C=O (on a carbon within the carbon chain)
-one

C=OOH
-oic acid
Ester functional group
C=OO
yl (alcohol stem) oate (carboxylic acid stem)-carbon with double bond to oxygen

Alkane + X (Cl2,Br2,F2,I2) –>
Alkane + X –> Haloalkane + H-X (Br,Cl,I,F)
reagents: UV light
Haloalkane –> Alcohol
Haloalkane + NaOH/KOH –> Alcohol + NaX/KX
Haloalkane –> Amine
Haloalkane –> amine + H-X
reagents: (NH3 and ethanol solution)
Primary alcohol oxidation –>
Partial oxidation –> aldehyde
Complete oxidation –> carboxylic acid
reagents: MnO4-/H+ or Cr2O72-/H+
Secondary alcohol oxidation –>
Secondary alcohol –> Ketone
reagents: Cr2O72-/H+ or MnO4-/H+
Esters are produced by — reactions
esterification / condensation reaction
–> ester
carboxylic acid + alcohol –> ester + WATER
reagents: conc. H2SO4
What undergoes addition reactions
alkenes
what undergoes substitution reactions
alkanes
Hydrolysis of ester–>
ester + H2O –> alcohol + carboxylic acid
reagent: H+
Hydrogenation of alkenes –>
alkene + H2 –> alkane
reagents: Ni catalyst and 150 degrees
Hydrohalogenation of alkenes –>
alkene + H-X (Br,I,F,Cl) –> Haloalkane
reagents : SLC or room temp
Halogenation of alkenes –>
alkene + X-X (Br2,I2,Cl2,F2) –> di-haloalkane
Alkene –> alcohol
alkene + H2O –> alcohol (hydration of alkene)
reagents: phosphoric acid catalyst, 300 degrees
