iing known #16: CllsBro2 Spectrum 25 10 Wavenumber ( H NMR in CDCs Not shown - a very broad singlet (1H) at 12 ppm which is 40 7 8 9

Hydrogens can be assigned according to the known structure. If completely unknown compound is there, assignment of hydrogen is difficult.

Still some key facts may help to assign them.

1. Follow 2n + 1 rule for multiplates.

2. See the chemical shift according to the atoms directly attached with hydrogen in the molecule.

3. Learn some approx. chemical valuues for the functional group.

Like in your NMR signal....2H , 2H are present according to the multiplates. which are adjacent to each other but in different chemical environment.
