Question

If someone explain how to find these unknowns..And what they are and how you got the answer. I am having a hard time really understanding NMR and IR.. Thanks in advance

Unknowns for 1H NMR Final Report 1) Chemical Formula: CaH;Br Зн 2H 2H PPM 2) Chemical Formul a: C; HgO IR: Strong broad peak 3300cm Зн 2H 2H H PPM 3) Chemical Formula: C,Ha0 IR: Strong broad peak at 3300cm зн Зн 2H PPM

Answer 1

NHR NMR is very easy topie, no need to worry too much to get Command on NMR, we should get Ideas On NHR No need Exact Value at least we should remember range given molecular Ilmulas C3HABA Calculda Number of unsaturation : 2C+Q+N-H-X values in it - shall M = 2x3+2 +0-7-1 20 24 24 Areas under curve give Intimation about . number of hydrogens number of hydrogy Splling give inflmation about Padsanent la Carbon de-Cha triplet Oh-Cty Br i adracent to this Cortons , So chemical shift Comes at w3.5 @hydrogen adrantent Carbon contains to triplet Br - Cth - CH₂ - CH3 - 2 2 hydrogens Contain Cemrbon is adoracent So truplet - - 24 M given molecules simule - Gitteo Number of ung cluction= ax3+2-0-80 elle all Number of 4 3 2 1 0 t CH2 th OH C4 C-Chy 014 =0 Combined All the fragments triplet Cahydrogens Contain Carbon ů HO-Ch-ab-Oh adajacent) + Triplet cu !
