You don’t have any answer chooses listed but i’ll say F isn’t a molecule because it stands for fluorine which happens to be an element that only has one atom when a molecule is supposed to have two or more atoms.
An ion-dipole interaction is the result of an electrostatic interaction between a charged ion and a molecule that has a dipole. It is an attractive force that is commonly found in solutions, especially ionic compounds dissolved in polar liquids. A cation can attract the partially negative end of a neutral polar molecule, while an anion attracts the positive end of a polar molecule. Ion-dipole attractions become stronger as the charge on the ion increases or as the magnitude of the dipole of the polar molecule increases.
This force of attraction is between an ion and a charge , it is weaker force than covalent bond and ionic bond . EX - The ion dipole interaction takes place between water and sodium ion , in it there is a small charge on oxygen molecule in water which is attracted by sodium charge .
Most commonly found in solutions. Especially important for solutions of ionic compounds in polar liquids.
A positive ion (cation) attracts the partially negative end of a neutral polar molecule.

Ammeter
<h3>
Explanation:</h3>
- Lets ask ourselves the following questions
What is an Ammeter?
- An ammeter is a device that is used to measure electric current in a circuit.
How is it used ?
- To measure the electric current the ammeter is placed in series with the components of the circuit and the reading on the ammeter is taken.
What is electric current?
- Electric current is a measure of the flow of electrons in a given circuit per unit time. It is therefore, the measure of the rate of flow of electrons in a circuit.
