Alkanes have single bonds while Alkenes have double bonds.
CnH2n+2 is the general formula for alkanes.
CnH2n is the general formula for alkenes.
1.The first four (i.e. c1 to c4) members of alkanes are gases,c5 to c17 are all colourless liquids, and higher than c17 are all colourless solids .
2. They are insoluble in water but soluble in organic compounds.
3. They are lighter than water (less dense) and float on it.
4. They are bad conductors of heat and electricity.
Alkanes and alkenes are two different homologous series and have different function groups. Alkanes are hydrocarbons that are saturated. Alkenes are hydrocarbons that are unsaturated.
Both alkane and alkene burn in the presence of O2 and gives these products Co2+H2O+ENERGY.
They are all hydrocarbons - they are composed of only carbon and hydrogen. They are all non-polar molecules, usually derived from petroleum.
Bromine water can test the difference between alkanes and alkenes because the bromine water turns colourless for the alkenes but doesnt change for the alkanes.
Alkenes are considered unsaturated because of the presence of a double bond between two or more carbons. A hydrocarbon is only saturated when there are only single bonded carbons present (Alkanes).
A line structural formula of alkanes would have single lines, which represent single bonds, between the symbols of the carbon and hydrogen atoms, and would show the arrangement of the atoms in a molecule of the alkane. Refer to the related links for illustrations of the first two alkanes, methane, CH4, and ethane, C2H6.
There are many different possibilities. A hydrocarbon is a saturated compound, so if you want to attach anything, e.g. chlorine, you have to drop off a hydrogen from the hydrocarbon. It wouldn't be a full molecule which attaches of course, as it needs a bond to attach by.
Alkynes are a similar functional group to alkanes and alkenes. The difference is that alkynes have a triple bond between two carbon atoms. The most well known alkyne is Ethyne (Acetylene) . Its structure is H-C///C-H . This gas is used in oxy-acetylene burners, and produces a very hot flame to melt metals. Other alkynes are Propyne ; H-C///C-CH3 But-1-yne ; H-C///C - CH2-CH3 But-2-yne ; H3C-C///C-CH3 Be careful when spellings these chemcial names , there is only ONE letter difference. alkAne, alkEne, & alkYne.
Bromine water can test the difference between alkanes and alkenes because the bromine water turns colourless for the alkenes but doesnt change for the alkanes.
Alkenes have at least one double bond between two carbon atoms; alkanes don't.
The difference between an alkane and an alkene is that: Alkanes have only single bonds between carbon atoms and are said to be saturated: when put in bromine water, the bromine water stays orange - formula: CnH2n+2; Alkenes: have one or more double bond(s) between carbon atoms and are unsaturated: when put in bromine water, the bromine water turns clear - formula: CnH2n.
Alkenes are considered unsaturated because of the presence of a double bond between two or more carbons. A hydrocarbon is only saturated when there are only single bonded carbons present (Alkanes).

For hydrocarbons with one or more single bonds between carbon atoms, the molecules are called alkanes, and the suffix is "-ane".With one or more double bonds, these molecules are called alkenes the suffix is "-ene".With one or more triple bonds, the molecules are called alkynes, and the suffix is "-yne".
an alkane does not have a double bond.... an alkene does have a double bond between carbons
Alkane: -ane. C-C interaction has single bond Alkene: -ene. C-C interaction has double bond Alkyne: -yne. C-C interaction has triple bond Least reactive alkanes are saturated hydrocarbons, while alkene and alkyne not. Alkanes undergo susbstitution reaction while others under go addition reactions rather. Alkanes rule is CnH2n+2 while alkene CnH2n and alkyne CnH2n-2.

Alkenes have a double bond between the carbon atoms (C=C) whereas alkanes have a single bond (C-C). so alkenes are unsaturated compounds, add aqueous solution of Bromine or KMnO4 to both the compounds the decolourization of these reagents confirms the presence of alkenes.
No, they are unsaturated as they contain double bonds
