What are the 4 alkanes?
The first four alkanes are methane, ethane, propane, and butane with the Lewis symbols shown below.
What is the formula of alkane alkene and alkyne?
Alkynes are the unsaturated hydrocarbons that have at least one carbon and carbon triple bond. The triply bonded carbon atoms are sp hybridized. The general formula for alkyne is CnH2n−2 , where n is any integer greater than 1. The simplest alkyne, ethyne has two carbon atoms and having molecular formula C2H2 .
What is 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 other name of alkene?
In chemistry, an alkene is a hydrocarbon containing a carbon–carbon double bond. Alkene is often used as synonym of olefin, that is, any hydrocarbon containing one or more double bonds. Two general types of monoalkenes are distinguished: terminal and internal. Also called α-olefins, terminal alkenes are more useful.
What is alkyne formula?
What is an example of an alkane?
Alkanes are saturated hydrocarbon consist of carbon and hydrogen only without any functional group. The general formula of alkane is C nH 2n+2. Example: methane (CH 4), ethane (C 2H 6), propane (C 3H 8) etc.
What type of bond is alkane?
Alkane Structure and Bonding. Alkane is a term used to describe a hydrocarbon that contains only single carbon to carbon bonds. The single bonds allow the carbon atoms to bond with as many hydrogen atoms as allowed by carbon’s bonding principles. Because of this, alkanes are referred to as “saturated” hydrocarbons.
Is alkane a compound?
Alkanes are chemical compounds, made of carbon and hydrogen. The simplest alkane is methane, which is made of one carbon atom and four hydrogen atoms.
