PPT-Intermolecular Interactions

Presented by Leticia Bonita Prince Newcastle University 4 th Year MChem Student Aims of Today Increase your understanding of intermolecular interactions Increase your spatial skills and awareness using software designed by the CCDC. IB Topic 4: Bonding. Carbon allotropes. pure carbon is covalently bonded in three of different forms (allotropes). graphite. diamond. fullerenes. To buy lots of super duper expensive carbon allotropes, . Intermolecular Forces • When molecules are attracted to other molecules by a weaker force (when compared to an ionic bond or a covalent bond holding a molecule together) • Intermolec INTERACTIONS. Intramolecular. Interaction. (. http://www.chem.ufl.edu/~itl/4411/lectures/lec_g.html. ). Intermolecular Interactions. (. http://www.chem.ufl.edu/~itl/4411/lectures/lec_g.html. ). Modelling. CA Standards. Students know . the atoms and molecules in liquids move in a random pattern relative to one another because the intermolecular forces are too weak to hold the atoms or molecules in a solid form.. The molecular compounds like water, ammonia, and carbon dioxide have different physical properties because of the intermolecular forces.. Comparison of all three phases:. Liquids & Solids. Liquids & Solids. ● . Phases and Phase Diagrams. ● Liquids and Liquid Properties. ● Intermolecular Forces. ● Heating Curves. ● Introduction to Solids. ● Cubic Packing Arrangements. ● Closest-Packed Structures. Chemistry 11. Ms. McGrath. Intermolecular Forces. The forces that bond . atoms. to each other within a molecule are called . intramolecular forces. . Covalent bonds and ionic bonds are an example of intramolecular forces.. Which one represents a liquid? Why?. Liquids have a definite . volume. , but not a definite . shape. . The particles are closer together than gases so the intermolecular forces are now a factor.. Liquids have a definite . . properties & interactions. Daley & . Daley. Chapter . 4:.

Inter. molecular. Intra. molecular. States of Matter. Attraction between molecules increasing. Intermolecular Forces . the forces between (among) individual particles (atoms, ions, molecules); they are weak relative to . intramolecular. forces (i.e. covalent and ionic bonds within a compound). Intermolecular forces are increasingly significant in this order:. . Department . of Pharmaceutics. 1. 26-Feb-16. Drug interactions . :. . These are said . to occur when the pharmacological activity of a drug is altered by the concomitant use of another drug or by the presence of some other substance. . Ryan . kiddey.
