sir, i dont understand how to choose the word root.can you please show me some more examples to name the compounds
i) In the following molecule, the longest chain has 6 carbons. Hence the root word is "hex-".
However the chain with more number of substituents (that with 3 substituents as shown in the following diagram) is to be taken as the parent chain.
Another example is as follows: There are two chains with 6 carbons. But the chain with the a double bond as shown in the diagram (II) is to be selected as the parent chain.
