What is the structural formula for 2-methylpropane?

Step 1: Understand that 2-methylpropane is an alkane, which means it is a saturated hydrocarbon with single bonds.
Step 2: Identify the main chain of the molecule. The name 'propane' indicates a three-carbon chain (C-C-C).
Step 3: The '2-methyl' part means there is a methyl group (CH3) attached to the second carbon of the propane chain.
Step 4: Draw the three carbon atoms in a row: C-C-C.
Step 5: Add the methyl group (CH3) to the second carbon. This gives you: C-CH3-C-C.
Step 6: Complete the structure by adding hydrogen atoms to each carbon to satisfy the tetravalency (four bonds) of carbon.
Step 7: The final structural formula is CH3-CH(CH3)-CH2-CH3.
