. Molecules with

the same molecular formula, but different atomic connections (structural formulas) are called

"constitutional isomers". See how many different alkanes, all with the same formula (C

) that you

can draw. After you draw them, write their names. You can draw line bond, condensed, or skeletal

structures (the key shows skeletal structures).
