Sorry didn't get to finish.

CH2 CH2

CH2 CH2

Each CH2 going from left to right has a single bond as well.

I think this is an alkane but I am not sure. I only think this because it only has single bonds of hydrogen and carbon.

Is this correct?
Yes. Hydrocarbons (only H and C) with all single bonds are alkanes. A double bond makes them alkenes and a triple bond makes them (hydrocarbons) alkynes.
Oh ok I understand thank you!
