We're supposed to try and figure out the structure of a compound based off the the following information:
δ: 2.4 2H triplet
δ: 2.1 3H singlet
δ: 1.5 2H triplet
δ: 1.3 6H singlet
δ: 0.9 3H triplet
>δ: 2.4 2H triplet
This is probably a CH2 group bonded to a carbonyl, which is suggested by the chemical shift, and another CH2.
>δ: 2.1 3H singlet
This is probably a CH3 group bonded to a carbonyl group, which is indicated by both the chemical shift and the fact that it is bonded to another carbon that has no hydrogens.
> δ: 1.5 2H triplet
I was thinking that this is CH2 next to another CH2 and .. maybe a carbonyl group or a t-butyl group? Or possibly next to two CH groups?
>δ: 1.3 6H singlet
This is the one that stumps me the most. Usually, when I see a chemical shift of 1.3 with 6H, my first guess is isopropyl, but the fact that it's a singlet is really throwing me off.
>δ: 0.9 3H triplet
This is almost certainly a CH3 group bonded to a CH2.
On the IR Graph, the information given is as follows:
2960 cm^-1: Transmission 72%
1714 cm^-1: Transmission 45%
The first IR reading indicates an alkane, while the second indicates a ketone.
That's about as far as I've gotten. Help please! D:
