Which of the following is the correct structure for 2-methylpropane?

Correct Answer: C5H12

Step 1: Understand that 2-methylpropane is a type of hydrocarbon called an alkane.
Step 2: Know that alkanes have a general formula of CnH2n+2, where n is the number of carbon atoms.
Step 3: Identify that 'propane' means there are 3 carbon atoms in the main chain.
Step 4: Recognize that '2-methyl' indicates there is a methyl group (CH3) attached to the second carbon of the main chain.
Step 5: Draw the main chain of 3 carbon atoms (C-C-C) for propane.
Step 6: Add a methyl group (CH3) to the second carbon of the main chain.
Step 7: Ensure that all carbon atoms have enough hydrogen atoms to satisfy their four bonds.
