HNMR splitting for this molecule. . .

I'm trying to figure out why this molecule shows two singlets and not 1 singlet and 1 doublet. Because of symmetry, the methyl H's would show up as 1 singlet and the H's on the ring would show up as one doublet right?

Image or molecular name?

Just posted 🙂 I had to edit the image.

the methyl H would be a singlet (with an integration of 6), and those on the ring would be 1 singlet with integration of 4?

(identical H cAnnot "see" (split) each other)

just like for ethane, you will not get 1 multiplet, but 1 singlet.

Thanks for clearing that up. I didn't know the last part.
