To determine the structures of compounds S and T, we first need to analyze the given information.

Compound T has an isomer of C4H8Cl2, which means it has 4 carbon atoms, 8 hydrogen atoms, and 2 chlorine atoms. The ^1H NMR spectrum of T consists only of two singlets with an integration ratio of 3:1.

From the integration ratio of 3:1, we can infer that one singlet corresponds to 3 equivalent protons, while the other singlet corresponds to 1 proton.

Since compound T has 8 hydrogen atoms in total, the singlet with an integration ratio of 3:1 must correspond to 3 equivalent protons, leaving the other singlet to correspond to the remaining 5 protons.

Therefore, the structure of compound T can be deduced as follows:
- The singlet with an integration ratio of 3:1 corresponds to 3 equivalent protons, which could be from a CH3 group.
- The other singlet corresponds to 5 protons, which could be from a CH2 group.

Thus, the structure of compound T is likely 1-chlorobutane (CH3CH2CH2CH2Cl).

Now, we need to determine the structure of compound S. Since compound S is an isomer of C4H8Cl2, it must also have 4 carbon atoms, 8 hydrogen atoms, and 2 chlorine atoms.

Given that compound T is 1-chlorobutane, compound S must be a different isomer of C4H8Cl2. One possible isomer of C4H8Cl2 is 2-chlorobutane (CH3CHClCH2CH3).

Therefore, the structures of compounds S and T are:
- Compound S: 2-chlorobutane (CH3CHClCH2CH3)
- Compound T: 1-chlorobutane (CH3CH2CH2CH2Cl)

Compound T:

The formula of T is C₄H₈Cl₂, and its ¹H NMR spectrum shows only two singlets with an integration ratio of 3:1. This suggests that T has two distinct sets of chemically equivalent protons, with one set containing three protons and the other set containing one proton.

One possible structure for T is 1,1-dichloroethane (CH₃CCl₂). In this compound, the three protons on the methyl group are chemically equivalent, and the one proton on the methylene group is chemically equivalent. The ¹H NMR spectrum of 1,1-dichloroethane would therefore show two singlets with an integration ratio of 3:1.

However, there is another possible structure for T that is also consistent with the ¹H NMR spectrum: 1,2-dichloroethane (ClCH₂CH₂Cl). In this compound, the two protons on each methylene group are chemically equivalent, and so the ¹H NMR spectrum would show two singlets with an integration ratio of 3:1.

Compound S:

Compound S is an isomer of T, so it also has the formula C₄H₈Cl₂, but it must have a different structure to T. One possible structure for S is 1-chloro-1-propene (CH₂=CH-CH₂Cl). In this compound, the three protons on the methyl group are chemically equivalent, and the two protons on the methylene group are chemically equivalent. The ¹H NMR spectrum of 1-chloro-1-propene would therefore show two singlets with an integration ratio of 3:1.

Another possible structure for S is 2-chloro-1-propene (CH₃-CH=CH-Cl). In this compound, the two protons on the methyl group are chemically equivalent, and the two protons on the methylene group are chemically equivalent. The ¹H NMR spectrum of 2-chloro-1-propene would therefore also show two singlets with an integration ratio of 3:1.
