Eight (8) compounds were synthesized during a course of 7 weeks lab. As a starter,
chalcone was made from Benzaldehyde and 4-ethoxyacetophenone. A part of chalcone was
brominated to make Dibromochalcone as a second compound. Anot

1) For C, H, O only, max IHD is observed when the number of H is zero (0).
The number of O atoms will not affect the IHD, as usual.
Thus, max IHD = n + 1, where n = # of C atoms.
We need to measure the NMR
Tetramethylsilane (TMS) is our
reference for 1H, 13C and 29Si.
The chemical shift (denoted )
varies in different chemical
= [ (obs TMS ) / TMS ] x 106
Chemical shifts depend on the
electronegativities of n

Old Tale of Chalcone
Once upon a time, there was a king named acetophenone and queen named
benzaldehyde. They didnt have an heir and began to worry as each day pass
