The structural formula CH3 CH2 CH3 corresponds to which alkane?

Explanation:
Counting the carbon atoms in the chain shows three carbons here: CH3-CH2-CH3. In alkanes, the name matches the number of carbons in the chain. One carbon is methane, two carbons is ethane, three carbons is propane, and four carbons is butane. The end carbons are CH3 and the middle carbon is CH2, giving the formula C3H8, which is propane.
