How many ways can hydrocarbons are classified?
Aliphatic hydrocarbons are divided into three main groups according to the types of bonds they contain: alkanes, alkenes, and alkynes.
Alkanes have only single bonds, alkenes contain a carbon-carbon double bond, and alkynes contain a carbon-carbon triple bond..
What is the general formula for a straight chain alkane?
Straight-chained and branched alkanes follow the same general formula: CnH2n+2. The smallest branched alkane is 2-methylpropane or isobutane (Pictures shown above).
What is the general formula of Cycloalkenes?
Cycloalkenes have the general formula CnH2(n-m). The letter m represents the number of double bonds. Thus, cyclopropene has the formula C3H4 while that of cyclobutene is C4H6. The properties of alkanes and alkenes are very similiar.
Why are alkanes flammable?
Why are alkane gases like propane so flammable considering that they are non-polar compounds? … Polar compounds often have low flash points because of the oxygen, but alkanes have very high heats of combustion, which makes them good fuels even if you have to heat them up a little more before they start burning.
What is the chemical formula of methane?
What are two examples of hydrocarbons?
Natural gas and fuels – Many of the natural fuel sources we use are hydrocarbons. Compounds like methane, butane, propane, and hexane are all hydrocarbons. Their chemical formulas consist of only carbon and hydrogen atoms, in a variety of ratios and chemical configurations. 2.
What is the general formula of Cycloalkynes?
A cycloalkyne consists of a closed ring of carbon atoms containing one or more triple bonds. Cycloalkynes have a general formula CnH2n−4.
What is the general formula for a straight chain alkane quizlet?
Explain why the general formula for an alkane, CnH2n+2, correctly predicts hydrocarbons in a homologous series. Each nonterminal carbon atom within the hydrocarbon chain bonds with two hydrogen atoms.
What is the functional group of alcohol?
Alcohol is an homologous series in which the compounds contain a functional group called the hydroxyl group (-OH). The general molecular formula for alcohols is CnH2n+1OH. Alcohols are all derivatives of hydrocarbons in which one or more of the hydrogen atoms in the hydrocarbon have been replaced by a hydroxyl group.
Why is the general formula for Cycloalkanes?
Each ring in a compound reduces the number of hydrogen atoms by 2 relative to an alkane because a ring contains an extra carbon–carbon bond and, therefore, two fewer carbon–hydrogen bonds. Thus, the general formula for cycloalkanes with one ring is CnH2n, the formula for compounds with two rings is CnH2n−2, and so on.
What group of hydrocarbons have the general formula CnH2n?
AlkanesAlkanes have the general formula CnH2n+2 and can be subdivided into the following three groups: the linear straight-chain alkanes, branched alkanes, and cycloalkanes. Alkanes are also saturated hydrocarbons.
Which hydrocarbon has the highest viscosity?

What is the general formula for a hydrocarbon?
They are composed entirely of single bonds and are saturated with hydrogen. The formula for acyclic saturated hydrocarbons (i.e., alkanes) is CnH2n+2. The most general form of saturated hydrocarbons is CnH2n+2(1-r), where r is the number of rings. Those with exactly one ring are the cycloalkanes.

Why is the general formula for an alkane is CnH2n 2?
The general formula of alkanes is C(n)H(2n+2) because all intermediate carbon atoms in a non-branched carbon chain are bonded to two hydrogen atoms: . . . … So, there are two hydrogens for each carbon, plus the two extra hydrogens at the beginning and the end of the chain.
