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 .

What is a homologous series AQA?

An homologous series is a family of compounds that all contain the same functional group(s) and differ in successive members by one -CH2- unit.

What is the homologous series of alkane?

The alkanes are a homologous series of hydrocarbons . This means that they have similar chemical properties to each other and they have trends in physical properties. For example, as the chain length increases, their boiling point increases.

What is the order of alkene?

R2C=CR2, R2C=CHR , R2C=CH2 , RCH=CHR and RCH=CH2.

What are the example of alkanes alkenes and alkynes?

→ Examples : Ethylene ( C2H2 ) or ethene; Pentene ( C5H10 ). Alkynes are unsaturated hydrocarbons which have atleast one carbon- carbon triple bond. Their general formula is CnH2n−2 . You can see that these have 2 hydrogen atoms less than their corresponding alkane.

What is the longest alkane?

The longest linear alkane is now C59H120, which is considerably longer than expected from the force-field results and remarkably different to the PM3 result.

What is an alkane group?

Alkanes are organic compounds that consist entirely of single-bonded carbon and hydrogen atoms and lack any other functional groups. … Alkanes are also saturated hydrocarbons. Alkanes are the simplest and least reactive hydrocarbon species containing only carbons and hydrogens.

What are the 2 major sources of alkanes?

The most important sources for alkanes are oil and natural gas. Oil is a mixture of liquid alkanes and other hydrocarbons.

How many alkyl groups are there?

There is only one alkyl group derived from methane and ethane. However, for a longer chain of carbon atoms, several isomeric alkyl groups are usually possible depending on which carbon atom “loses” a hydrogen atom. Many of these alkyl groups are known by their common names.

Is ch3 a methyl?

A methyl group is an alkyl derived from methane, containing one carbon atom bonded to three hydrogen atoms — CH3. In formulas, the group is often abbreviated Me. … It is a very stable group in most molecules.

What is the name of this alkane ch3 ch3?

Ethane is an alkane comprising of two carbon atoms.
