Question

what is the iupac name of this structure?
​

Answer 1

Answer:

your answer

Explanation:

Give the IUPAC name for the following compound:

Identify the functional group. ...

Find the longest carbon chain containing the functional group. ...

Number the carbons in the longest chain. ...

Look for any branched groups, name them and assign the number of the carbon atom to which the group is attached.

Answer 2

The longest carbon chain in the molecule consists of eight atoms and is numbered in such a manner that the double bond gets the lowest numbering.

This can be done by beginning the numbering from the bottom right of the molecule, such that the the first double bond gets the lowest numbering of one.

So, we continue to number, as the longest carbon chain has eight atoms, so the root word will be octa.

The ethyl ( -CH2-CH3) groups are attached to the fourth and the fifth carbon atoms, so the prefix will be 4,5-Diethyl .

The double bonds are hence present at positions 1,4 and 6, so the complete suffix will be 1,4,6-triene .

So, the complete IUPAC name will be 4,5-Diethylocta-1,4,6-triene

So the correct option is (2).
