Where does it say the naming process? :)
This website may help you in understanding the naming process for molecules : http://www.woodrow.org/teachers/chemistry/links/chem1/namingcomp.html
Thank you. :)
But 2 methyl heptene is right? @MathBlonde
Wai, it has to be hexane
The formula given in the attachment isn't right, the second carbon -CH- has incomplete bonding.
Is it 2 methyl hexane?
-you start counting from the end of the chain closest to the double or triple bond. -you always start counting from the carbon that will make the chain the longest -recognize that it is an alkyne so that will go into the suffix NAMING Process (For me at least) -so name the longest chain first, it is 7 carbons long thus it is hept -the tripple bond is on the 3rd carbon from one end and the 4th carbon from the other end, thus we say it is the 3rd carbon from the end we always start counting from the end closest to the triple bond. -we recognize that the tripple bond means it is an alkyne so it has the suffix yne so far we have: 3-heptyne -notice that there is a methyl group on the second carbon thus we have to add that as a prefix so we have the chemical 2-methyl-3-heptyne
it is not 2 methyl heptene because ene is the suffix for alkene which is a double bond, furthermore you did not specify that the double bond (should be triple bond) is on the third carbon, so we are left to assume that the first carbon has the double bond. 2 methyl heptene: |dw:1346210983686:dw|
furthermore, if you would have specified that heptene was on carbon 3, you would have to specify if it was cis or trans as the double bond version of this chemical has steroisomers
@akitav I would just accept it as a typo but good eye
