The most useful information you can get from a
For example, you have the
Is its structure (a) CH₃CH₂COOCH₂CH₂CH₃, (b) CH₃CH₂COOCH(CH₃)₂, or (c) CH₃COOC(CH₃)₃?
You quickly calculate that
(a) has 6 different C atoms;
(b) has two equivalent C atoms, so there only 5 different carbon environments;
(c) has three equivalent C atoms, so there only 4 different carbon environments.
The spectrum shows 5 carbon signals, so the ester must be (c) isopropyl propanoate.
