Question

Determine the maximum number of peak(s) you would expect to observe in a ¹³C-NMR spectrum 1-pentene, assuming that each distinct chemical environment gives rise to a peak.

Answer 1

We have 5 carbons in the chain in 1-pentene molecule. A double bond is present between the carbon 1 and 2.

All the 5 carbons have distinct chemical environment; it will show 5 peaks in the 13C- NMR spectrum.

Answer 2

Hi Mika R.,

So, assume that the double bond definitely influences all the carbons around it, even as far as 3 carbons away .... each of the carbons will be distinct, right?

or Google 1-pentene 13C NMR directly.
