PPT-Allotropes of Carbon and Intermolecular Forces

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 . Kevin Leslie . Pd6 . What is a Allotrope. Allotropes are two or more forms of an element that have distinctly different physical or chemical properties. The picture below is a . A pencil made of Graphite. 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. 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 - bonding theories. Lewis Structures and Bonding. Use NASB to draw dot diagrams. . N – electrons . need. ed to fill valence (8 or 2). A- electrons . available. in atom . S – electrons shared = N – A . Repasy. . Per. 6. Allotropes. Allotropes are…. Two or more forms of an element that have distinctively different physical or chemical properties. . Ex: color of a diamond, or the arrangement of atoms in Phosphorous. . 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. Science Discussion Group. “. Graphene. ”. Ann Clark & Linda Estruch. 15 November 2013. What are we going to talk about?. Introduction . Basic . chemistry . – Carbon from diamond to . graphene. 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 . 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:. 1. If I put 2 molecules into a sealed flask, what could happen?. They ignore each other.. They LOVE each other – they’re attracted to each other. They HATE each other – they repel each other. 2. Ryan . kiddey. University of . akron. ret program . 2018. Lesson: That’s slick!
