Why are alkenes unsaturated?

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...

Take a simple olefin, $"2-butene"$. Clearly its formula is $C_4H_8$ or $H_3C-CH=CH-CH_3$. Because the double bond extends above and below the plane of the molecule, the pendant methyl groups cannot...

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...

Alkenes and alkynes are called unsaturated compounds because the carbon atoms do not have as many hydrogen atoms as they possibly could. A saturated compound contains a chain of carbon...

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...

Non polar molecules are made of atoms that have small differences in electronegativity. Carbon has an electronegativity of 2.5 while Hydrogen has an electronegativity of 2.2. This is a...

It was derived from the original French "gaz oléfiant" which means "oil forming gas". Olefin was the original term, "alkene" was coined later to give a more systematic naming...

Alkenes, olefins, have the $"ONE DEGREE OF UNSATURATION...."$ ...............A very useful idea that is used to rationalize the formulae of organic compounds is the $"degree of unsaturation"$. An alkane is...

The main difference between alkanes and alkene is that alkanes have only single carbon-carbon bonds, while alkenes have at least one double carbon-carbon bond in them. Saturated fats have...
