Physical science Intermolecular ForcesFor each type of intermolecular force, do the following:•Write the definition in your own words.•Draw a diagram/illustration showing how the force works. (Must be hand-drawn, not digital.)•Give at least two examples of substances or scenarios where it occurs.•Color-code your diagrams for clarity.draw the diagram guide (hand drawn)I will report it if it is not drawn

1. Hydrogen BondingDefinition: A strong attraction between a hydrogen atom bonded to a highly electronegative atom (like O, N, or F) and another electronegative atom nearby.Examples: Water (H₂O) Ammonia (NH₃)Diagram Guide: Draw two water molecules side by side. Use blue for oxygen, white for hydrogen. Show a dotted line between the hydrogen of one molecule and the oxygen of the other. Label it “Hydrogen Bond.”2. Dipole-Dipole ForcesDefinition: Attraction between molecules that have permanent dipoles (positive and negative ends).Examples: Hydrogen chloride (HCl) Acetone (CH₃COCH₃)Diagram Guide: Draw two HCl molecules. Use red for Cl (negative side), green for H (positive side). Show arrows pointing from positive to negative ends. Label the attraction between them as “Dipole-Dipole Force.”3. London Dispersion Forces (LDF)Definition: Weak forces caused by temporary shifts in electron density, present in all molecules but dominant in nonpolar ones.Examples: Noble gases like Helium (He) Nonpolar molecules like Methane (CH₄)Diagram Guide: Draw two methane molecules. Use gray for carbon, white for hydrogen. Show temporary dipoles with faint arrows or shaded areas[tex].[/tex]Label the attraction as “London Dispersion.”Tips for finding hand-drawn-style diagrams on Google: Search using phrases like “hand-drawn hydrogen bonding diagram”, “dipole-dipole force sketch”, or “London dispersion forces classroom drawing” and look for images that have pencil-like lines, simple molecule shapes, and labeled arrows — these usually come from student notes or textbook scans and are perfect for your project.
