Yes if the molecule's chirality is only one side.
If it's around 50/50, then no.
Same with any carbo-hydrates found in comets and asteroids :
Both side 50/50 = molecules build randomly
One side is more than 90/10 = A molecular automaton build it

Certain compositions perhaps, but not just liquid hydrocarbons. Titan has more hydrocarbons than Earth and its presence can be explained without life.
