Based on the information provided, we can deduce the structure of Compound S as follows:
1. The singlet peak corresponds to a methyl group (3 hydrogens) or a methoxy group (3 hydrogens).
2. The triplet peak corresponds to a methylene group (2 hydrogens).
3. The quartet peak corresponds to a methine group (2 hydrogens).
Putting this information together, we can propose the following structure for Compound S:
CH3-CH2-CH(Cl)-CH2-Cl
This structure satisfies the given proton n.m.r. spectrum with a singlet (3H), a triplet (2H), and a quartet (2H) peaks with an integration ratio of 3:3:2.

Possible structure of Compound S:
- 1,1-dichloro-2-methylpropane
Proton NMR data:
- Singlet (3H): The methyl group (CH3)
- Triplet (3H): The methylene group (CH2) adjacent to the chlorine atoms
- Quartet (2H): The methylene group (CH2) between the methyl and chlorine groups
Explanation:
- The singlet arises from the three equivalent protons on the methyl group.
- The triplet arises from the three equivalent protons on the methylene group adjacent to the chlorine atoms. Each proton on this methylene group has two neighboring protons on the methyl group, resulting in three lines in the triplet.
- The quartet arises from the two equivalent protons on the methylene group between the methyl and chlorine groups. Each proton on this methylene group has one neighboring proton on the methyl group and three neighboring protons on the other methylene group, resulting in a quartet.
Integration ratio:
The integration ratio of 3:3:2 corresponds to the number of protons in each group:
- 3 protons in the methyl group (singlet)
- 3 protons in the methylene group adjacent to the chlorine atoms (triplet)
- 2 protons in the methylene group between the methyl and chlorine groups (quartet)
- 1,1-dichloro-2-methylpropane
