They both contain 4 carbon atoms.

Explanation:

They also both consist in two forms (only one of each is pictured below).

2-butanol (or butan-2-ol):
Imagine the OH and H switching place, and you'll get the mirror image of the one shown. The second C atom is called 'chiral'.
One is form called the L-L− and the other the D-D−form.

2-butene (or but-2-ene):
The H or CH3 groups could also be at the same side of the double bond. The one shown is the trans-trans−, the other the cis-cis− form.
