Question

steps to do IUPAC naming of long chained compounds

Answer 1

Here is a simple list of rules to follow. Some examples are given at the end of the list. 

1.Identify the longest carbon chain. This chain is called the parent chain.

2.Identify all of the substituents (groups appending from the parent chain).

3.Number the carbons of the parent chain from the end that gives the substituents the lowest numbers. When compairing a series of numbers, the series that is the "lowest" is the one which contains the lowest number at the occasion of the first difference. If two or more side chains are in equivalent positions, assign the lowest number to the one which will come first in the name.

4.If the same substituent occurs more than once, the location of each point on which the substituent occurs is given. In addition, the number of times the substituent group occurs is indicated by a prefix (di, tri, tetra, etc.).

Answer 2

1. Identify the longest carbon chain containing the functional group.
2. Start numbering the carbon atoms so that the functional group gets the least possible number.
3. Using suffix and prefix for the given functional group.


For example.

CH3-CH2-COOH
It's IUPAC name is
Ethan-1-oic acid.


Hope u understood...
