Answer 1

The  missing compound is attached in the diagram below.

Answer:

1-fluoro-5-methyl-6,6-dimethyloctane

Explanation:

Naming an organic compound by using the IUPAC system have some guided rules to adhere to.

The International Union of Pure and Applied Science (IUPAC) put forward a system of naming which related the name of the compound to its molecular structure. Similarly,from the structure of the compound, one can easily suggest the name for the compound.

Rules guiding the IUPAC nomenclature are:

1. Select the longest continuous carbon chain as the root hydrocarbon and name it according o the number of carbon atoms present, adding the appropriate suffix to indicate the principal substituent group.

2. Number the carbon atoms in the root hydrocarbon from the end which will give the lowest number to the substituents. (the substituent can be an alkyl group, a radical, or halogen group)

3. If the same substituent is present two or more times in a molecule, the number of this substituent is indicated by the prefix : di for (2), tri for (3); tetra for (4) ,penta for (5) etc.

4. If there is more than one type of substituent in the molecule, the substituents are named according to the alphabetical order but where there are mixed substituents, the inorganic are named first.

5. In selecting and numbering the longest continuous chain, the functional groups are given preference over substituents . This implies that the number are given the smallest possible number.

Having said that:

From the required attached below;

The parent name for the carbon compound is called Octane since 8 carbons are present in the chain and there is no double bond or triple bond in the compound.

Next the numbering of the carbon chain will start from the carbon next to the Fluorine atom (F) because it is the inorganic substituent  present in the compound which therefore have higher preference over the organic substituent.

So; the fluorine is one the carbon atom 1

we have another organic substituents present in the compound which is one methyl on carbon atom 5 and two separate methyl on carbon atom 6.

So; The proper IUPAC name for the compound is:

1-fluoro-5-methyl-6,6-dimethyloctane
