C2H4- has a planar struture

as it has a double bw the two carbon atoms(C=C)

so it cannot rotate so that it cannot show conformation hence it has a planar structure......!!!

C2H4 is planar in structure. as C atoms are sp2 hybridised. thus the three bondings lie in a plane.

in C2H6 and CH4 C atoms are sp3 hybridised and thus a tetrahedral 3d shape forms or u can say that one bondind lies out of plane.

C2H2 is linear in shape.
