What is an alkane series?

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. The general formula means that the number of hydrogen atoms in an alkane is double the number of carbon atoms, plus two.

What is the general formula of alkane series?

CnH2n+2 Alkynes have one or more carbon-carbon triple bonds. Alkenes and alkynes are called as unsaturated hydrocarbons. Alkanes have the general formula of CnH2n+2 where n is the number of carbon atoms.

What are the first 10 alkanes?

These are organic molecules that consist only of hydrogen and carbon atoms in a tree-shaped structure (acyclic or not a ring). These are commonly known as paraffins and waxes. Here is a list of the first 10 alkanes. List the Simplest Hydrocarbons.

methane CH4
butane C4H10

How do you use the general formula of alkanes?

0:35 10:37

What is the example of alkane?

Methane (CH4), ethane (C2H6), propane (C3H8) and butane (C4H10) are the first four alkanes. Methane gas, whose molecular formula is CH4, is the simplest alkane.

What is the general formula of alkynes?

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 3 letters do all alkanes end in?

The names of all alkanes end with -ane. Whether or not the carbons are linked together end-to-end in a ring (called cyclic alkanes or cycloalkanes) or whether they contain side chains and branches, the name of every carbon-hydrogen chain that lacks any double bonds or functional groups will end with the suffix -ane.

What is the general formula of alkane 1?

The general formula for the alkanes is C nH 2n+2 (where n is the number of carbon atoms in the molecule).

What is general formula of alcohol?

The general formula for the alcohols is C nH 2n+1OH (where n is the number of carbon atoms in the molecule).

What does the general formula mean?

A general formula is a type of empirical formula that represents the composition of any member of an entire class of compounds.

What are the 4 smallest alkanes?

List of straight-chain alkanes

Number of C atoms Number of isomers Molecular Formula
1 1 CH4
2 1 C2H6
3 1 C3H8
4 2 C4H10

How do you remember the first 10 alkanes?

For example the first 10 alkanes in order are , Methane, Ethane, Propane, Butane, Pentane, Hexane, Heptane, Octane, Nonane and Decane. These can be memorised with “Many elephants prefer blue pinapples.

What are the first three alkanes?

We introduced the three simplest alkanes—methane (CH 4), ethane (C 2H 6), and propane (C 3H 8)—in Chapter 4 “Covalent Bonding and Simple Molecular Compounds”, Section 4.6 “Introduction to Organic Chemistry”. They are shown again in Figure 12.1 “The Three Simplest Alkanes”.

What are the first four alkanes called?

The first four alkanes are methane (CH4), ethane (C2H6), propane (C3H8) and butane (C4H10).

What are 10 common hydrocarbons?

Common hydrocarbons:

  • Methane(CH4)
  • Ethane(C2H6)
  • Propane(C3H8)
  • Butane(C4H10)
  • Pentane(C5H12)
  • Hexane(C6H14)

How are alkanes classified?

Alkanes 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.

What is general formula of aldehyde?

Answer: Aldehyde is a chemical compound with a functional group -CHO. The general formula of alkene is CnH2n+1 so the general formula for aldehyde will be CnH2n+1CHO or CnH2nO.
