The correct Answer is:
To determine the IUPAC name of the given compound, we will follow these steps: ### Step 1: Identify the Longest Carbon Chain First, we need to find the longest continuous carbon chain in the structure provided. In this case, we can count the carbon atoms: 1. CH3- (1) 2. CH2- (2) 3. CH- (3) 4. CH- (4) 5. CH3 (5) 6. CH3 (6) The longest carbon chain consists of **6 carbon atoms**. ### Step 2: Number the Carbon Chain Next, we will number the carbon atoms in the chain. According to IUPAC rules, we should give the lowest numbers to the substituents and functional groups. Starting from the end of the chain closest to the functional group (OH), we number the carbon atoms as follows: 1. C1 (OH) 2. C2 (Cl) 3. C3 (CH3) 4. C4 (CH3) 5. C5 6. C6 ### Step 3: Identify Substituents and Functional Groups Now we identify the substituents and the functional group: - **Functional Group**: Hydroxyl group (OH) on C1 - **Substituents**: - Chlorine (Cl) on C2 - Two Methyl (CH3) groups on C3 and C4 ### Step 4: Construct the Name According to IUPAC nomenclature: - The suffix for the hydroxyl group (OH) is "ol". - The prefix for the chlorine substituent is "chloro". - The prefix for the methyl groups is "methyl". Since we have two methyl groups on C3 and C4, we will use "dimethyl". ### Step 5: Assemble the Name We will now put together the name in the correct order: - Start with the substituents in alphabetical order (chloro before methyl). - Include the number of each substituent. - End with the root name based on the longest carbon chain and the functional group. Thus, the name will be: - 2-chloro - 3,4-dimethyl - 1-hexanol (since the longest chain has 6 carbons and the functional group is on C1) ### Final IUPAC Name Putting it all together, the IUPAC name of the compound is: **2-chloro-3,4-dimethyl-1-hexanol** ---
To determine the IUPAC name of the given compound, we will follow these steps: ### Step 1: Identify the Longest Carbon Chain First, we need to find the longest continuous carbon chain in the structure provided. In this case, we can count the carbon atoms: 1. CH3- (1) 2. CH2- (2) 3. CH- (3) ...
