1
Identify the different types of hydrogen environments in the molecule ethyl chloride (CH\_3CH\_2Cl). Each unique environment corresponds to a distinct signal in the \( ^1H \) NMR spectrum.
Look at the methyl group (CH\_3) hydrogens. Since all three hydrogens are attached to the same carbon and have the same neighbors, they are chemically equivalent and will give one signal.
Examine the methylene group (CH\_2) hydrogens next to the chlorine atom. These hydrogens are in a different chemical environment from the methyl hydrogens because of the electronegative chlorine, so they will produce a separate signal.
Confirm that there are no other types of hydrogens in the molecule that would create additional signals. In ethyl chloride, only the CH\_3 and CH\_2 groups have hydrogens, so there are two distinct environments.
Conclude that the \( ^1H \) NMR spectrum of ethyl chloride will show two signals, one for the methyl hydrogens and one for the methylene hydrogens.
