What is the IUPAC name for the following structure and which option represents it?

Question

ScanSolve AI Tutor · Accepted Answer

Step 1: Identify the longest continuous carbon chain. The longest continuous chain of carbon atoms has 4 carbons. This makes the parent alkane butane. Step 2: Number the carbon chain to give the substituent the lowest possible number. If we number from left to right: C₁ − C₂(CH₃) − C₃ − C₄ The methyl group is on carbon 2. If we number from right to left: C₄ − C₃(CH₃) − C₂ − C₁ The methyl group is on carbon 3. The lowest possible number for the substituent is 2. Step 3: Identify and name the substituents. There is one methyl group (CH₃) attached to the main chain. Step 4: Combine the substituent name and position with the parent alkane name. The methyl group is at position 2, and the parent chain is butane. Therefore, the IUPAC name is 2-methylbutane. Step 5: Compare with the given options. The calculated name matches option (A). The final answer is A
