Sir, What is a parent chain atom and how can we identify them in a structure?
The chain which contains the highest number of C-atoms.
Identification of the parent hydrocarbon chain . This chain must obey the following rules, in order of precedence:
- It should have the maximum number of substituents of the suffix functional group. By suffix, it is meant that the parent functional group should have a suffix, unlike halogen substituents. If more than one functional group is present, the one with highest precedence should be used.
- It should have the maximum number of multiple bonds
- It should have the maximum number of double bonds.
- It should have the maximum length.
