Question

give iupac name of the question.

Answer 1

The IUPAC name of the given compound is 3- Ethyl Hexane.

Answer 2

Notice that the chain going up is longer than the horizontal chain.

This means, we have to number their carbons.

Adding the longest chain, we get 6 carbon atoms, and we notice that there is no double or triple bond.

Hence the root name: hexane

Now we also see CH₂-CH₃ in the horizontal chain. This can be said as C₂H₅, that is ethyl, and it lies on the 3rd carbon. So, 3-ethyl. That's the prefix.

Hence, the IUPAC name: 3-ethyl hexane
