Which formula represents an alkane?

(1) C2H2 (3) C3H4 (2) C2H4 (4) C3H8

Alkanes are a category of organic compounds. The generic formula for alkanes is CnH2n+2.

What does it mean? Let say a molecule has 3 carbons. In order to calculate the number of hydrogens we must plug in 3 and get 2*3+2 = 8. Therefore the formula for this alkane would be C3H8.
