Question

The proton NMR spectrum in Figure $19-39$is for an organic compound containing a single atom of bromine. Identify the compound.

Short answer

The compound is${\mathrm{CH}}_3-{\mathrm{CH}}_2-\mathrm{Br}$.

Step-by-step solution

Triplet and Quadrat

The spectrum indicates that the existence of two kind of protons.

Triplet at$\delta ={1.69}_{}$suggest the existence of$-{\mathrm{CH}}_3$collection connected to$-{\mathrm{CH}}_2$group and$-{\mathrm{CH}}_2$collection adjacent to$-{\mathrm{CH}}_3$suggest by the existence of a quadrat at$\delta =3.34$.

conclusion 

The above statement denotes that the compound is${\mathrm{CH}}_3-{\mathrm{CH}}_2-\mathrm{Br}$.
