Name the molecule C2H6.

Explanation:
Two carbon atoms in a saturated hydrocarbon fit the alkane pattern CnH2n+2, so with n = 2 you get C2H6. The two-carbon alkane is named ethane. This matches the given formula. Methane has one carbon (CH4), propane has three carbons (C3H8), and butane has four (C4H10), so they don’t fit C2H6.
