Shown below are interactions that occur between ions and polar compounds (cyclopentyl alcohol, dimethyl ether, dimethyl sulfide, and water). Examine the types of intermolecular forces in which each of the following molecules participate, then rank the following interactions between molecules and ions from the weakest to the strongest based on those intermolecular forces and trends in electronegativity.

Question
Shown below are interactions that occur between ions and polar compounds (cyclopentyl alcohol, dimethyl ether, dimethyl sulfide, and water). Examine the types of intermolecular forces in which each of the following molecules participate, then rank the following interactions between molecules and ions from the weakest to the strongest based on those intermolecular forces and trends in electronegativity.
The image displays four chemical structures arranged from left to right, labeled from "Weakest" to "Strongest." 

1. **First Structure (Weakest):** 
   - This is a molecule involving a sodium ion (Na⁺) bonded to a methylsilicon group (CH₃)₂Si. 

2. **Second Structure:**
   - This features a molecule with a positive dipole on an oxygen atom (δ⁺) bonded to two hydrogen atoms (H), and a fluoride ion (F⁻), indicating hydrogen bonding with the fluoride.

3. **Third Structure:**
   - This structure shows a molecule formed by three ethyl groups (H₂C–CH₂), with one group attached to a carbon chain. The chain includes an oxygen atom bonded to a hydrogen atom (δ⁺) with hydrogen bonding to a fluoride ion (F⁻).

4. **Fourth Structure (Strongest):**
   - This consists of a lithium ion (Li⁺) bonded to a methoxide ion (CH₃O⁻), shown with a negative dipole on the oxygen atom (δ⁻).

Below the structures, there is an option box stating, "The correct ranking cannot be determined," accompanied by "reset" and "help" buttons.
