The allene molecule has the following Lewis structure: H2C=C=CH2. Are all four hydrogen atoms in the same plane?
The allene molecule has the following Lewis structure: H2C=C=CH2. Are all four hydrogen atoms in the same plane? If not, what is the spatial relationship? Explain.

I know they are not in the same plane but i don't know how they are arranged and how to describe it.

The C atom is sp2 hybridized which makes it trigonal planar. Thus, the left CH2 has atoms in the same plane and the other CH2 has all three atoms in the same plane BUT the TWO CH2 groups are perpendicular to each other. Here is a picture.
