How are alkanes named?

The names of all alkanes end with -ane. … Alkanes with unbranched carbon chains are simply named by the number of carbons in the chain. The first four members of the series (in terms of number of carbon atoms) are named as follows: CH4 = methane = one hydrogen-saturated carbon.

Which is the first member of alkanes?

Methane gasMethane gas is the first member of the homologous series of alkanes. The valency of a single carbon atom is satisfied by four hydrogen atoms which form single covalent bonds.

What is alkynes general formula?

In organic chemistry, an alkyne is an unsaturated hydrocarbon containing at least one carbon—carbon triple bond. The simplest acyclic alkynes with only one triple bond and no other functional groups form a homologous series with the general chemical formula CnH2n−2.

Is c2h4 an alkyne?

We know that ethylene has one element of unsaturation, which is the double bond, so we can figure out that ethylene has only four hydrogen atoms and its chemical formula is C2H4. … Alkynes are unsaturated hydrocarbons in which carbon atoms are joined by triple covalent bond. C4H10 is an Alkene.

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”.

What is the homologous series of alkynes?

The alkynes comprise a series of carbon‐ and hydrogen‐based compounds that contain at least one triple bond. This group of compounds is a homologous series with the general molecular formula of C n H 2 n‐‐2 , where n equals any integer greater than one.

Is c2h2 an alkyne?

Acetylene (systematic name: ethyne) is the chemical compound with the formula C2H2. It is a hydrocarbon and the simplest alkyne. … As an alkyne, acetylene is unsaturated because its two carbon atoms are bonded together in a triple bond.

What is the simplest alkyne?

The simplest alkyne—a hydrocarbon with carbon-to-carbon triple bond—has the molecular formula C2H2 and is known by its common name—acetylene (Figure 13.6. … Acetylene (ethyne) is the simplest member of the alkyne family. Acetylene is used in oxyacetylene torches for cutting and welding metals.
