CBSE Class 10 Science Carbon and its compounds homologous series
|
As soon as you see a -OH functional goup attached to an alkyl group you should recog nise it as an Alcohol . And the given alkyl group contains 4 carbons so it could be none other than butanol.
As the given compound contains 4 carbons and a -OH functional group which shows its name to be Ethanol.
All the members of a homologous series show the similarity in their chemical properties as they contain same functional group.
As according to the given structure you could tell as you see the tiple bond and five carbons attached to each ather it shows the arrangement of an alkyne that is pentyne.
As the given compound contains an aldehyde functional group so the suffix al should be added after Pentane removing (e) from it .
There is an upgradation in the physical properties of the members of a homologous series as we move forward in a homologus series.
As we can see in the given depiction of the organic compound a halogen so that chlorine is attached to the pentyle ( Alkyle Group) it gives us its IUPAC name as Chloropentane.
The difference between the molecular massess between two adjacent members is 14 u.
The IUPAC name for the given organic compound is pentane as deplcted by the figure 10_04_014_07
In order to name this compound you should first count how many carbons are there and then look for the functional group attached to it to decide its name according to the IUPAC standards.
