What is the general formula for an alkane?

What is the general formula for an alkane?

CnH2n+2
Alkanes have the general formula of CnH2n+2 where n is the number of carbon atoms.

What is the general formula for alkenes GCSE?

C nH 2n
The general formula for the alkenes is C nH 2n, where n is the number of carbon atoms in the molecule. Decene is an alkene. Its molecules contain 10 carbon atoms .

What are alkanes BBC Bitesize?

Alkanes are saturated hydrocarbons. This means that their carbon atoms are joined to each other by single bonds. This makes them relatively unreactive, apart from their reaction with oxygen in the air – which we call burning or combustion. Butane. Like other homologous series, the alkanes show isomerism.

What are alkanes used for GCSE?

Alkanes are used as fuels. Combustion of alkanes and other organic compounds can be complete or incomplete.

What is a general formula in chemistry?

Definition of general formula : a chemical formula applicable to a series of compounds (as MNO2 for metallic nitrites, ROH for alcohols, CnH2n + 2 for alkanes where n is an integer)

What is general formula of alkyne?

Alkynes are hydrocarbons which contain carbon-carbon triple bonds. Their general formula is CnH2n-2 for molecules with one triple bond (and no rings).

What is the structure of alkanes?

The alkanes comprise a series of compounds that are composed of carbon and hydrogen atoms with single covalent bonds. This group of compounds comprises a homologous series with a general molecular formula of C n H 2 n+2 , where equals any integer.

What are alkenes GCSE?

Alkenes are a homologous series of hydrocarbons that contain a carbon-carbon double bond. The number of hydrogen atoms in an alkene is double the number of carbon atoms, so they have the general formula C n H 2 n .

Why is the general formula of alkenes different to the general formula of alkanes?

Alkenes have the general formula C nH 2n , which means for every carbon atom there are double the number of hydrogen atoms. Alkenes are different to alkanes because they contain at least one double carbon bond.

What are alkane give its general molecular formula and important uses?

By saturated hydrocarbons, it means alkanes have single hydrogen and carbon atoms in their chemical formula. Formula of alkane is CnH2n+2. Methane, propane, ethane, and butane are four alkanes. Let us learn in detail about Alkanes and their physical properties below.

What is the general formula of alkane 11th class?

General formula of Alkane is CnH2n+2.

What is alkane explain with example?

Alkanes are saturated hydrocarbons. By saturated hydrocarbons, it means alkanes have single hydrogen and carbon atoms in their chemical formula. Formula of alkane is CnH2n+2. Methane, propane, ethane, and butane are four alkanes.

What are alkenes BBC Bitesize?

Alkenes are a homologous series of hydrocarbons that contain a carbon-carbon double bond. The number of hydrogen atoms in an alkene is double the number of carbon atoms, so they have the general formula C n H 2 n . For example, the molecular formula of ethene is C 2 H 4 , while for propene it is C 3 H 6 .
