Types of Chemical reactions
Substitution:
replace elements with other elements
( 2 reactant-2 products)
1) formation of alkyl halide:
alkane+ halogen => alkyl halide + h-halogens
2) formation of alcohol
alkane + halogen => alkyl halide
alkyl halide + NaOH => alcohol + ionic salt
Addition:
addition of another element (without deletion/elemination)
( 2 reactants 1 product)
1) hydration:(changes alkenes to alcohol)
a substance combines with water
2) hydrogenation: (addition of H2)
to treat with hydrogen
3) monohalgenation:
chemical reaction that involves the addition of one halogens to a compound or material.
4) dihalogenation:
chemical reaction that involves the addition of 2 halogens to a compound or material.
Elimination:
removes element completely
( 1 reactants-2 products)
1)dehydrogenation:
a chemical reaction that involves the removal of hydrogen from an organic molecule.It is the reverse of hydrogenation.
2) dehalogenation:
a chemical reaction that involves the cleavage of C-Halogen bond to form product.
3) dehydration of alcohol:
(removal of H2O)
conversion that involves the loss of water from the reacting molecule or ion
Oxidation:
gaining pg oxygen/ losing hydrogen
Tertiary
alcohol -> oxidation
Secondary
alcohol -> ketone -> no more oxidation
Primary
alcohol -> aldehyde -> carboxylic acid
Reduction:
losing oxygen/ gaining hydrogen
keynote -> aldehyde
aldehyde -> keynote
Condensation:
removal of H2O from 2 molecules
esterification:
he reaction between alcohols and carboxylic acids to make esters.
