Why are alkenes and alkynes called unsaturated compounds?

Sigma bonds can rotate around and shift. This makes isomers of non-substituted alkanes impossible because the atoms can shift back and forth. Pi bonds, like those in double bonds, can't...

Alkanes have no DEGREES of unsaturation, and have formula $C_nH_(2n+2)$... See and

Alkanes have single bonds between carbons in a hydrocarbon. A quick way to recognize an alkane is the general formula: $"C"_ n"H"_(2n+2)$. Examples: methane, $"CH"_4$ ethane, $"C"_2"H"_6$...

Structural isomerism is determined by the $C-C$ connectivity of the molecule. Geometric isomers have the same $C-C$ connectivity, but differing geometries. Thus, a simple olefin such as $"2-butylene"$ clearly has...

Alkanes are saturated hydrocarbons which are formed by single bonding between the carbon atoms. They are mostly used for heating, cooking, and electricity generation. The alkanes which have...

First you must know the basics The most basic explanation (that you would hear in chem. 101) is that alkynes are more reduced (less saturated) than alkanes (and alkenes as...

Hydrocarbons are organic compounds which only consist of carbon ($C$) and hydrogen ($H$) as their elements. Alkanes are a group of acyclic, saturated hydrocarbons. These are contain carbon -...

Alkanes are saturated; they contain the maximum number of (energy rich) $C-H$ bonds. An alkane has general formula $C_nH_(2n+2)$. Each 2 hydrogens LESS than this formula corresponds to a double...

Consider alkanes ; Also called Paraffin They have single bonds present in their structure and are called saturated compounds. They have a general formula CnH2n+2 Carbon is sp3...

For the compounds to be isomers they must have identical condensed formula. Alkane with $n$ $ C$ atoms : $C_nH_(2n+2)$ Alkene with $n$ $ C$ atoms : $C_nH_(2n)$ Alkyne with...
