Question

Question: Give the IUPAC name for each compound.

Short answer

Answer

1. 4-isopropylheptane
2. 3-ethyl-3-methylpentane
3. 4,4-diethyl-5-methyloctane

Step-by-step solution

Newman projection

The two bonded carbons show a Newman projection with their groups.

IUPAC names

a. The given Newman structure has two bonded carbon atoms. The first priority is given to that carbon where the tri substitution of the carbon is located. Therefore, the correct name and structure are shown as:

4-isopropylheptane

b. The given Newman structure has two bonded carbon atoms. The first priority is given to that carbon where the tri substitution of the carbon is located. Therefore, the correct name and structure are shown as:

3-ethyl-3-methylpentane

c. The given Newman structure has two bonded carbon atoms. The first priority is given to that carbon where the bulky substituents are located. Therefore, the correct name and structure are shown as:

4,4-diethyl-5-methyloctane
