COMPETENCY STANDARDS

Classify hydrocarbons compounds based on its structure and relationship with the properties of compounds

BASIC COMPETENCIES

Write a simple reaction to the compounds alkanes, alkenes, and alkynes (oxidation reactions, addition reactions, substitution reactions and elimination reactions)

Understanding of organic compounds and macromolecules, to determine the reaction and synthesize macromolecules as well as its usefulness

INDICATOR

WHAT ARE THE GROUPS IN

HYDROCARBONS ?

ALKANES

ALKENES

ALKYNE

SUBSITUTION REACTIONreplacement of atom in

hydrocarbon compounds by atom of other compounds

Can replaced by

CH4(g)+ Cl2(g)

CHH

H

H + Cl Cl

Example

CH3Cl(aq) + HCl(aq)

EASY, RIGHT ??

ADDITION REACTIONcompounds with

double or triple bond

single bond

+

CH2= CH2 + HCl → CH2—CH2 + H—Cl → + CH2—CH2

H Cl

Hydrogen atoms will be bound on the number of carbon atoms more hydrogen

Markovnikov Laws

("The rich will get richer")

ELIMINATION REACTION

compounds with single bond

double or triple bond

YOU ARE MY BEST STUDENT !!

REDUCTION-OXIDATION REACTION

The reaction is accompanied by changes in oxidation

stateOxidation Increase oxidation

state

Reduction Decreases oxidation state

H─C─O─H + ½ O2(g) → H─C = O + H2O

H H

H

Oxidation Reaction

Oxidation of methanol to form formaldehyde

-2 0 0 -2Oxidation

Reduction

H─C = O + H2O → H─C─O─H + ½ O2

H H

H

Reaction of formaldehyde to form methanol

Reduction Reaction

-2 00 -2Oxidation

Reduction

CH3 – O – CH3 + 3O2 2CO2 + 3H2OCombustion Reaction
