Level 2 Structure and Bonding
Flashcards do conjunto (12)
- 1Chlorine molecules (Cl₂) form single covalent bonds between chlorine atoms. Explain what the 'single covalent bond' means? Hint- Valence ElectronsA pair of electrons is shared between the Cl atoms so that each Cl atom has 8 valence electrons. A single covalent bond is formed.
- 2Oxygen molecules (O₂) form double covalent bonds between oxygen atoms. Explain how this bonding occurs?Two pairs of electrons are shared between the O atoms so that each O atom has 8 valence electrons.
- 3Draw a Lewis Structure diagram for H₂, HCl and N₂
- 4Draw a Lewis Structure diagram for H₂O, CO₂ and CH₄
- 5What shape is made when there are 4 electron pairs around a central atom, all of which are bonding pairs? What is the bond angle?Tetrahedral, Bond angle is 109⁰
- 6What shape is made when there are 3 electron pairs around a central atom, two of which are bonding pairs and one is a lone pair? What is the bond angle?V-shaped or Bent, Bond angle is >120⁰
- 7What shape is made when there are 2 electron pairs around a central atom? What is the bond angle?Linear, Bond angle is 180⁰
- 8What shape is made when there are 4 electron pairs around a central atom, 3 of which are bonding pairs, and 1 lone pair? What is the bond angle?Trigonal Pyramid, Bond angle is at >109⁰
- 9What shape is made when there are 3 electron pairs around a central atoms, all of which are bonding pairs? What is the bond angle?Trigonal Planar, Bond angle is at 120⁰
- 10What shape is made when there are 4 electron pairs around a central atom, 2 of which are bonding pairs and 2 of which are lone pairs? What is the bond angle?V Shaped or Bent, Bond angle is >109⁰
