LT-D1029 SCORE ER-NIDA-09267 LIQUID multiplet doublet Double click on the image above to open in an acrobat reader. 0000

Answer 1

IR spectrum

There are sp3 C-H stretching presents around ~ 2950 cm-1.

There is no IR active functional group are present apart from sp3 C-H and sp3 C-C stretching.

1H NMR spectrum

The peak at ~3.3 ppm doublet is CH2 peak lies between CH and Br.

The peak at ~ 1.0 ppm doublet is dimethyl group attached to CH

The middle peak is C-H peak

using all the information we can deduce the structure

Br Y 1-bromo-2-methylpropane Chemical Formula: CH Br Molecular Weight: 137.02 ChemNMR 1H Estimation 3.22 3.22.12 0.93 Br~ 0.93 PPM
