Answer:
7–methyl–3,5–octanediol.
Explanation:
To name the compound given in diagram above, we must:
1. Identify the functional group of compound.
2. Locate the longest continuous carbon chain in the compound. This gives the parent name of the compound.
3. Identify the substituent group attached to the compound.
4. Locate the position of the substituents by giving it the lowest possible count.
5. Combine the above to get the name of the compound.
Now let us name the compound. This can be done as follow:
1. The functional group of the compound is –OH i.e alkanol (alcohol). It is located at carbon 3 and 5.
2. The longest continuous carbon chain is 8 i.e octane. But the presence of the OH will change the name to octanol.
3. The substituent group attached to the compound is –CH3 i.e methyl.
4. The methyl group is located at carbon 7.
5. Therefore, the name of the compound is:
7–methyl–3,5–octanediol
