2x2 Rubik's cube - an unsolution

Probability Level 1

Is it possible to arrange by normal moves a standard 2x2 rubik's cube such that on every side there are no repetitions of colors?

Bonus: How about 3x3 or 1x1 cubes?

Yes No

We need a PROOF and not an EXAMPLE.

An example is a proof in this case.

We would need a rigorous proof if we were to prove it false.

We might want proof if we were asked to specify how many different answers are possible. I suppose the 1x1 'Rubix cube' is trivial, with only one solution, and no non-solution.
