Teaching CSIR NET Mock Test Series Chemical Sciences Structure Determination of Organic Compounds 1h NMR and 13c NMR Spectroscopy
Consider the following compound where 3Jab and 3Jpc represent three bond coupling between Ha & Hb and Hb & Hc protons, respectively.
In two different scenarios,
I. 3Jab < 3Jbc and
II. 3Jab = 3Jbc
the multiplicity of Hb proton, respectively, will be
1
i = quintet; ii = quartet of doublets
2
i = quartet of doublets; ii = quintet
3
i = triplet of triplets; ii = quartet of doublets
4
i = triplet of triplets; ii = quintet
