Rules of Naming Organic compounds

1) The longest continuous chain of carbon atom which may or may not be straight is selected as parent chain.
    In case, two long chain of equal lengths are possible, the chain with maximum substituent as parent chain.

2) The longest chain is numbered as 1, 2, 3,...... etc. starting from that end which gives the lowest possible number to the substituent.
    In case, the parent chain has two or more substituent, numbering must be done in such a way that the sum of the locants (number that locates the position of substituents) on the parent chain is the lowest possible number.
