- Butane
(You might find some sources stating that it is multiplet. Technically that is correct, but we treat it like it is a quartet) - Methyl propanoic acid
- 3-methylbutan-2-amine
(the N-H can go anywhere between 1.0 and 4.5 so doesn’t appear here. It has a relative intensity of 2 and may or may not split) - Propanone
- Isopropylethanoate / methylethylethanoate
- But-2-ene-1,4-diol.
