What is the functional group of an alkene?
carbon-carbon double bond
The functional group in an alkene is a carbon-carbon double bond. The functional group in an alkyne is a carbon-carbon triple bond.
How do you write a condensed formula for an alkene?
It is named using the same stem as the alkane having the same number of carbon atoms but ends in -ene to identify it as an alkene. Thus the compound CH2=CHCH3 is propene….13.1: Alkenes- Structures and Names.

What are the general formula for alkane alkene and alkyne?
Alkanes have the general formula of CnH2n+2 where n is the number of carbon atoms. Alkenes have the general formula CnH2n. The general formula for alkynes is CnH2n-2. Acetylene is the simplest alkyne with the formula as C2H2.

Which is the correct formula for an alkene?
Nomenclature of Alkenes The general formula of alkenes is C n H 2n where n- 2, 3, 4, 5, … … According to the IUPAC system, the names of alkenes have a suffix-ene, and the prefix depends on the number of carbon atoms. Some names of the alkenes are as follows:
What is the formula for the Alkane Cycloalkane?
Cycloalkane: CnH 2n A fully saturated hydrocarbon, an alkane, has general formula CnH 2n+2: n = 1, methane; n = 2, ethane; n = 3, propane. BY reason of their formula alkanes are said to HAVE NO DEGREES of UNSATURATION. Where the formula is CnH 2n or CnH 2nOm, each 2 hydrogens LESS than 2n +2 represents a degree of unsaturation.
What is the formula for a fully saturated alkane?
A fully saturated hydrocarbon, an alkane, has general formula CnH 2n+2: n = 1, methane; n = 2, ethane; n = 3, propane. BY reason of their formula alkanes are said to HAVE NO DEGREES of UNSATURATION. Where the formula is CnH 2n or CnH 2nOm, each 2 hydrogens LESS than 2n+2 represents a degree of unsaturation.
