  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.).  

5.If there are two or more different substituents they are listed in alphabetical order using the base name (ignore the prefixes). The only prefix which is used when putting the substituents in alphabetical order is iso as in isopropyl or isobutyl. The prefixes sec- and tert- are not used in determining alphabetical order except when compared with each other.  

6.If chains of equal length are competing for selection as the parent chain, then the choice goes in series to:

a) the chain which has the greatest number of side chains.

b) the chain whose substituents have the lowest- numbers.

c) the chain having the greatest number of carbon atoms in the smaller side chain.

d)the chain having the least branched side chains.  

7.A cyclic (ring) hydrocarbon is designated by the prefix cyclo- which appears directly in front of the base name.


dhana232323: plzz mark me as brainliest
jaijaat2510: sry but i have asked rules not about nomenclature
jaijaat2510: never mine i do
jaijaat2510: but after 2-3 days as only 1 had ans. this que. so there is no option of brainliest....it will apper after some days the i will mark

Answer:

IUPAC Rules for Alkane Nomenclature

Find and name the longest continuous carbon chain.

Identify and name groups attached to this chain.

Number the chain consecutively, starting at the end nearest a substituent group.

Designate the location of each substituent group by an appropriate number and name.
