Why is there a duplicate hydrocarbons single, double and triple?Answer: because the hydrocarbons are divided into saturated hydrocarbons and unsaturated hydrocarbons.1. Hydrocarbon saturated / saturated (alkanaadalah the simplest hydrocarbon. Hydrocarbons is composed entirely of a single bond and bound with hydrogen. General formula for saturated hydrocarbons is CnH2n +2. Saturated hydrocarbons are the main composition on fossil fuels and is found in the form of straight or branched chain . Hydrocarbons with the same molecular formula but different structural formulas called structural isomers.2. Unsaturated hydrocarbons / no saturated) are hydrocarbons which have one or more double bonds, either duplicate or triplicate. Hydrocarbons having double bonds called alkenes, with the general formula CnH2n. Hydrocarbons having triple bonds called alkynes, with general formula CnH2n-2.
Although carbon is just one element of many elements in the periodic system, but can be the carbon atom covalently bonded to another carbon atom and the other elements in a variety of ways so that they can form many different compounds beegitu almost infinite number. Carbon and its compounds can be divided into enpat types:
a. Primary C atom: atom C 1 atom C binding to anotherb. Secondary C atom: C atom that binds two other C atomsc. Tertiary C atom: C atom that binds the other three C atomsd. Atom C quarter: C atom that binds the other four C atoms
Carbon DAPT form more compounds than any other element because not only can carbon atoms form a single carbon bonds, duplicate and triplicate, but also bias related to one another to form a chain and ring structures.. Based on the type of bonda. Saturated bond, if all the carbon bonds are single bonds ().Example

 
b. Unsaturated bond, if the bond contains 2 () and duplicate 3 () on a carbon - carbon.Said to be saturated because of the double bond, either in 2 or 3 copies are still able to undergo termination of bond.Example:

 
Besides distinguishing hydrocarbon compounds with other compounds is that these compounds though are from elemental carbon and hydrocarbons but can have different properties.The properties of compounds alkanes
1) C1-C4 gaseous at room temperature, C5-C17 liquid at room temperature, C17 + + solid at room temperature2) Increasing the number of atoms greater Mrnya C and boiling point.3) The more the smaller branches boiling point4) Alkanes easily soluble in organic solvents but sparingly soluble in water5) oxidation of alkanes is eksotermik26) Alkanes can act with halogen substitution7) long-chain Alkanes can undergo elimination reactions
The properties of alkenes
1) The more C atoms, the greater Mrnya, higher boiling point2) The interest low gaseous at room temperature, the interest rate was high liquid and solid form3) Easily soluble in organic solvents, but soluble in water4) Alkanes can act adducts with halogen

 
The properties of the alkyne
1) The increasing number of C atoms Mrnya greater, the higher the boiling point.2) alkyne adduct can react with halogens
