I've spent the past day trying to figure out the structure for the given formula C₆H₁₂O from the given HNMR and for the life of me, I don't know if I'm doing something wrong or I just don't have a deep grasp of HNMR, but I can't figure out the structure. I think it's mainly the overlapped set that's confusing me. I read online somewhere that the 3H overlap could be a CH₂ overlapping CH or OH but I didn't learn anything like that so I'm uncertain about this, so if anyone could explain what this means, I'd really appreciate it. Thanks.

What I have so far:

There should be a double bond in there somewhere since the IHD is 1.

The 3H set around 1 should be a -CH₂-CH₃

The 3H set around 1.5 should be -CH3 with 1 neighboring H so either a -CH(-C)-CH₃ with no H's on the (-C) or -CH=CH₃.

The 1H set around 3.3 should be a CH with 3 H neighbors and alpha to O atom so CH₃-CH(-C)-O- with CH's fourth substituent being a C with no H's or it could be -CH₂-CH(-CH)-O- maybe?

The 2H set around 2ppm is either a quartet or a pentet with an overlapping 3H singlet? I'm already confused about it overlapping so I hope someone could explain what this could mean.

The closest I've gotten was
but there's a vinylic H in there so that's clearly not it...

IHD (index of hydrogen deficiency) informs you about the possible presence of double bonds or rings. In the case of your compound, double bonds can form C with C or O.
The NMR spectrum is computer-simulated with poor resolution and the smallest peaks from the weaker multiplets may not be visible. The compound in no way contains the double bond C = C.

What about a ketone?
