ETHYL PROPIONATE NMR, carbonyl is dad and oxygen mom, a methyl gets more attention
Dedicated to all moms in the world
C=O group is dad
O atom is mom
Carbonyl is dad and oxygen mom hence c labelled methyl has higher chemical shift and gets a little more attention
NMR IS EASY
A chemical has Formula: C5H10O2
Rule 2, omit O, gives C5H10
5 - 10/2 + 1 = 1 degree of unsaturation.
Look for 1 pi bond or aliphatic ring.
The band at 1740 indicates a carbonyl, probably a saturated aliphatic ester. The bands at 3000-2850 indicate C-H alkane stretches. The bands in the region 1320-1000 could be due to C-O stretch, consistent with an ester.
