What is the strongest intermolecular force in ibuprofen?
The strongest intermolecular force present in ibuprofen is dipole-dipole interactions. Ibuprofen contains polar covalent bonds due to the differences in electronegativity between the atoms, leading to the formation of partial positive and negative charges. These partial charges allow ibuprofen molecules to attract each other through dipole-dipole interactions.

What types of bonds are present in the water molecule?
The water molecule is held together by polar covalent bonds between the oxygen and hydrogen atoms. Additionally, water molecules can form hydrogen bonds with each other due to the partial positive and negative charges on the hydrogen and oxygen atoms, respectively.
Why lithium fluoride is a neutral compound even though it is made up of ions that have posotive and negative charges?
Lithium ions have a charge of +1 and fluoride ions have a charge of -1. The formula unit for lithium fluoride is LiF, which means that the lithium and fluoride ions are present in a 1:1 ratio. So the positive and negative charges cancel each other, and the compound lithium fluoride is neutral.
Are elements that make up a compound always present in the same proportions?
No, elements in a compound are not always present in the same proportions. The ratio of elements in a compound is determined by its chemical formula.
What is the strongest intermolecular force in ibuprofen?
The strongest intermolecular force present in ibuprofen is dipole-dipole interactions. Ibuprofen contains polar covalent bonds due to the differences in electronegativity between the atoms, leading to the formation of partial positive and negative charges. These partial charges allow ibuprofen molecules to attract each other through dipole-dipole interactions.
Are there polar covalent bonds present in NH3?
Yes, there are polar covalent bonds present in NH3 because there is a difference in electronegativity between nitrogen and hydrogen. Nitrogen is more electronegative than hydrogen, causing the shared electrons to be pulled closer to nitrogen, creating a partial negative charge on nitrogen and partial positive charges on hydrogen.
Does ICl have ionic or covalent bonds?
ICl has both ionic and covalent bonds. The bond between iodine and chlorine is predominantly covalent, while the overall structure of the molecule exhibits ionic character due to the partial charges present on the atoms.
What forces are present in a three charge system?
In a three-charge system, the forces present are the electrostatic forces of attraction or repulsion between the charges. These forces are determined by the magnitudes and signs of the charges, as well as the distances between them, according to Coulomb's Law.
What factors do you need to consider in writing the formula of a compound?
When writing the formula of a compound, you need to consider the charges on the ions involved, ensuring they balance to maintain electrical neutrality. You also need to determine the ratio of each element present in the compound based on the lowest common multiple of the charges. Finally, simplify the ratio if necessary to represent the compound with the smallest whole numbers.
Is KF compound expected an ionic compound?
Yes, KF (potassium fluoride) is an ionic compound. It is formed from the reaction between a metal (potassium) and a nonmetal (fluorine), resulting in the transfer of electrons from potassium to fluorine, leading to the formation of ions with opposite charges that are held together by electrostatic forces.
Is the ionic compound between barium and oxygen present in one-to-one ratio?
Yes.
When are subscript used in formulas for ionic compunds?
Subscripts in formulas for ionic compounds are used to denote the ratio of ions in the compound. They represent the number of atoms of each element present in the compound to balance the charges. The subscripts are used to show the simplest whole-number ratio of ions in the compound.
Does the coulomb force that one charge exerts on other charges change if the other charges are brought nearby?
First of all, one charge doesn't exert force on other charges. The forces always occur in pairs ... a pair of equal and opposite forces between every two charges. The strength of those forces is proportional to the product of the two charges, and inversely proportional to the square of the distance between the two charges. So yes, if the distance between two charges were to change, then the coulomb force between them would change. If new, additional charges happen along, then there are forces between every two charges present. The forces between the original two don't change.
Why is octane non polar?
Octane is nonpolar because it consists of only carbon and hydrogen atoms bonded together through nonpolar covalent bonds. Since there is no difference in electronegativity between carbon and hydrogen atoms, there are no partial charges present, making the molecule nonpolar.

What is the relationship between the molar mass and the composition of a compound?
The molar mass of a compound is directly related to its composition. The molar mass is the sum of the atomic masses of all the elements in the compound. The composition of a compound refers to the types and amounts of elements present in it. Therefore, the molar mass provides information about the composition of a compound by indicating the relative amounts of each element present.
